Instead of just sharing "battles" from the best streaks, I'm going to share a loss too.
I knew it'd be bad from the moment I saw Marowak.

Remember how I said I almost always use Leech Seed on Turn 1? Nope, not this time! Marowak is probably one of the few Pokemon that can OHKO. Thick Club Outrage is terrifying even without a Dragon weakness. I switched to Duraludon for Reflect and Outrage dealt over half. Reflect let Duraludon endure the second hit and I let her Rest because I can't. Outrage ended and confused Marowak. I don't want to complain about the confusin nerf in Gen 7, but a fifty fifty chance would be a lot nicer than a 1 in 3 right now...
I need Leech Seed and am expecting them to use Bonemerang so I switch back to Appletun but they hurt themself in confusion instead. I try to use Leech Seed and Outrage does over half health! Protect stalls a precious turn lets Leech Seed heal to the point where I know Appletun would be able to take another Outrage... if Reflect hadn't worn off that turn... I switch back to Duraludon and she takes a lot of damage. She's not going to survive long enough to wake up. I Gigantamax to make it takes two Outrages to KO her and let her get KOed. There was no avoiding that loss.
I send out Dragalge and use Toxic. Outrage OHKOs.
Appletun came back out and used Protect. Marowak snapped out of confusion but gets confused again by Outrage ending. There's one turn left.
I either need Double Protect or Marowak to hurt itself in confusion.
Tentacruel

lives up to its name in Restricted Sparring. A Poison type with Black Sludge and Sword Dance that could have Liquid Ooze or Clear Body is evil. Even if it's not that strong, that's a very cruel combo that can easily end me. Fortuantly, it didn't have Liquid Ooze and only used Sword Dance once. To my amazement, +2 Cross Poison doesn’t KO after Recover and Leech Seed. Add in Protect to heal the extra damage from the one Critical Hit and, I CAN NEVER DIE! Then it used another Sword Dance... I hope they're out of Cross Poisons and, nope. Not out, but I don’t have much longer left... And I jinxed it. +4 dealt as much a +2 Crit and Poisoned Appletun immediately. ;_; There’s only two turns left and it’s Double Protect or die. There's a longer delay between a move failing and the "But it failed." than between using a move and its animation and it's taking longer than... Wait, what? It worked!? I’m cheating fate. I can’t believe I’m winni- The last Pokemon was Accelgor.

I might have had a chance with full HP and it would've been a joke if Marowak hadn't KOed everyone else. Can't complain though. It's fair after cheating death twice.
Streak Over at 9 Wins
I don't remember if this was in the streak I'm showing off or not, but I have a pic of Appletun against Meowstic. Appletun was frozen and at 48/217 HP. You know something's a joke when it has a Super Effective move and you still try to thaw a frozen Pokemon at low health against it.
The first "Battle" worth sharing in my best streak was the 7th. The lead, Clawitzer,

is strong, but it only has Water Pulse and laughable coverage. Wait, isn’t one of the other moves Dragon Pulse? Okay, this is the one time I can be terrified by the coverage... Doesn’t stop me from laughing at Dragon Pulse being the only coverage unless you count Terrain Pulse though.
Duraludon had a bit of damage so I don’t know for sure, but Dragon Pulse looked like it did about half. (I was at my laptop and had to check the Damage Calculator to see if it really did half. 77-91 (43.5 - 51.4%) Duraludon sucks!) It’s Gigantamax or die! I’m going to hope he can endure another Dragon Pulse because hoping for 3 Max Guards is useless. That never hap- It happened. After all 3 Max Guards working, I used Rest and... Oh, Duraludon went first... and Clawitzer dealt a tiny bit over half... It’s not a 2HKO because of Leftovers, but I still have to sacrifice Duraludon...
Appletun’s Protect stalls the final turn and next is Grapploct...

I tried to use Recover and go first because they used Circle Throw. That’s lucky. The problem is it dealt respectable damage and Dragalge is weak to Stomping Tantrum. They’re strong enough that I have to risk Toxic. Dragalge went first and poisoned them and they use Taunt instead of Stomping Tantrum!
I switched to Dragalge and they used Circle Throw to make me switch again on their final turn. I have to hope their last Pokemon is something I can beat and I’m feeling like the odds are good because Grapploct was probably the better of their two Pokemon. Their last Pokmeon was Thievul. Can’t they remove the Leppa Berry? Meh. I’m healing after this, so don’t care.
Leg 1: 7 "Battles"
I may have been able to save Duraludon if I realized she was faster and used Screech before Rest, but I only had that chance because of Triple Max Guard. It's a fair loss and a leg of 7 is impressive for Status Move Only.
"Battle" 8 started with Tangrowth,

but it was easy enough that I didn't take screenshots or notes other than, "Thanks for Grassy Terrain!"
Mienshao,

however, was a different story. I used Protect to block Fake Out then Leech Seed missed. It’s not a big deal because of Grassy Terrain, but High Jump Kick dealt a tiny bit over half damage. Oh, and Grassy Terrain just ran out. Did it heal enough to stop High Jump Kick from being a 2HKO? I use Protect to make the one miss then chose Recover and... 7 HP left! Holy crap. Another Protect makes another High Jump Kick miss for a self KO. In hindsight, switching Dragalge might have been better than keeping Appletun in.
The last Pokemon had funnier notes because Miltank

only knows Thunderbolt and Whirlpool. I might have been worried if Appletun hadn't Recovered from 7 HP, but I wouldn't have had to. I try Leech Seed even though they could have Sap Sipper and they go with Thunderbolt. I wasn't paying complte atention, but Thunderbolt made me think, “What did that do?” The loss of HP made me think, “I don’t think it did do.” I switched to Dragalge for Toxic because of Milk Drink letting them use endure longer and use more Thunderbolts then switched between Duraludon and Dragalge because I didn't care if either of them got Paralyzed. I didn’t need Leech Seed. Leftovers and Black Sludge are healing off the Thunderbolts.
“Battle” 9 is a big one because that's what the last streak got and the lead looked promising. Lunatone

has Cosmic Power and Moonlight, but isn’t Shiny and doesn’t know Toxic or Recycle. I laugh at your Lunatone as much as my Lunatone would laugh at you. I guess Moonblast is Super Effective or something, but I’m not sure about that because it dealt less than half.
Cloyster

is way scarier than Lunatone. I always fear Skill Link and now that I think about it, I'm pretty sure Cloyster has had Skill link almost every time, like maybe two or three times that it didn't. That's annoying luck. Anyway, Leech Seed landed, which is nice, but Icicle Spear hit 5 times and came very close to KOing Appletun! I used Protect then switched to Duraludon because she should be able to endure, I guess... My faith is low after Clawitzer. Why’d they use Shell Smash on the turn I switch!? *Sigh* It's Gigantamax or die and I might die either way... I chose the Screech PP Max Guard and they used... Razor Shell? Uh... Okay. Do I have a chance? Max Guard failed and they didn’t lower my Defense with Razor Shell. I have a chance. Cool. Duraludon can use Reflect and Rest.
I let Duraludon stay in after a Razor Shell lowered their Defense, (I usually don’t have a Damage Calculator open, but it was still up after checking Clawitzer.) but the second Defense drop made me switch to Appletun. Leech Seed healed what Razor Shell dealt but I didn’t know if Cloyseter had one or two turns left. I Protect and they faint!
Their last Pokemon was Blissey.

I have Leech Seed. It healed 40 HP. Per turn. Duraludon needed healing, so I'll let you put two and two together.
There wasn't much challenge in "Battle" 11, but it had a few interesting moments. Beartic

used Rain Dance and Sword Dance, but I used Leech Seed and switched to Dragalge for Haze. (All Beartic has is Liquidation and Superpower, no Ice attacks.) I would've used Toxic on Lycanroc-Day

if its coverage wasn't Psychic Fang. I switched to Appletun instead and Lycanroc loves to use Stealth Rock and spam Roar. Leech Seed and Leftovers heals more than Stealth Rock deals, so it's only a problem for Appletun. Even then, it's not much of one.
I seem to be really good at tempting fate with this team. For example, right when I started thinking the second leg was doing good, "Battle" 12's lead turned out to be Abomasnow,

the one Grass type that laughs at this team. I immeditly switched to Duraludon for Reflect and she lost a third of her health from the first Ice Punch. She outspeeds and gots to use Reflect before taking another Ice Punch, so she only went down to half HP. I switched to Dragalge for Toxic and they used Ingrain during the switch, which felt lucky, then...
Critical Hit!
They outspeed and KOed. I have to stall an Ice type to Struggle. 0_o
I never thought I’d say this, but I believe in you Duraludon! (I’m sorry for bashing on you and Screech is awesome.) I had her use Rest even when she’s above half HP because you can’t be frozen when asleep, but I still use Screech after waking up so Reflect wears off then renewed Reflect every time between Rests. I switched to Appletun when they ran out of Ice Punches to save Duraludon’s HP and Rest PP. I’m so glad I figured out Exeggutor wouldn’t work before this because Ice Shard would deal over half. Thick Fat is awesome! MY FAT PIE CAN NEVER DIE!
As awesome as stalling Abomasnow to Struggle felt, it's not over yet. The second Pokemon was Porygon-Z.

The good news it it doesn’t have any Super Effective Moves and likes to use Conversion. The bad news is it still has Base 135 SpA and a 50/50 chance of having Adaptability because it doesn’t have Download. Shadow Ball is dealt a less than half to Appletun and I can alternate between Recover and Protect, so that wouldn't be a problem unless they lowered my Special Defense, which they did. After that, it was disturbingly powerful. Recover and two turns of Leech Seed almost full healed it, but I’m so glad I only had to take one.
After Porygon-Z came Miltank...

with Sap Sipper... and I don’t have Toxic... I can't lose unless I try, but it's still annoying. I’m healing after this, so why not Duraludon Screech Spam? It has 50 PP left and they can’t out damage Leftovers healing until they use Whirlpool. I’d laugh at that move, but it’s not funny after Gyrados seemingly using it at random. Screech had 11 PP left when Miltank KOed itself with Struggle.
Leg 2: 5 "Battles"
It was cut short by a Critical Hit, but it happens and is less annoying than loss by Leech Seed missing. 5 is still pretty good for Status Moves Only.
I got a breather for "Battle" 13. Morpeko,

is annoying because of Parting Shot being unpredictable and a combination of tons of PP and changing forms every turn making it take over a half hour if you stall it to Struggle, (IIRC, it was 40 Minutes.) but not a potential streak ender. I protect against Fake Out then they use Parting Shot and the Leech Seed I was using landed on Runerigus.

If that’s their best, I’ve already won. It was. Their last Pokemon was a Lighting Rod Pincurchin.

I still don’t get how every team is doing better than Electric.
“Battle” 14's Mantine

knowing Rest made me use Confide a few times, but it wasn't any real trouble. Knowing Hurricane would be scary for Appletun if it didn't love using Rain Dance first. That's a risk free Leech Seed.
Exploud's

Boomburst dealt a little under half to Appletun, which means death after their Throat Spray. There’s no way I don’t need Light Screen and Confide. I switched to Duraludon and used Light Screen, but I’d forgotten that Exploud knows Focus Blast. Fortunately, it missed. Even if it hit, Duraludon went first so Light Screen would’ve made it not horrible. It went better than expected. I switched to Dragalge to take the next Focus Blast, which somehow hit, and used Haze because its PP are less valuable than Confide's then spammed Confide. I'd forgotten about Soundproof, but it had Scrappy instead.
I have a question about the last Pokemon. What’s more annoying, Thievul’s

Knock Off not letting you use Appletun or Poison Point activating when you’re trying to use Toxic? It’s hard to tell when they’re just kind of annoying from the last Pokemon, especially when they spam Parting Shot after you Rest then use Dynamax to take less on the incoming damage from attacks that didn’t happen. Torment was also a little annoying because I had to use some of Dragalge’s slightly more valuable Confide PP instead of just Haze.
“Battle” 15 started with staring down death, Weavile.

It’s been a good run. Might as well use Protect to waste a PP... They used Triple Axel? Cool. I’d probably risk trying Leech Seed if Appletun was at full HP instead of 168/217. I can switch to Duraludon and get Taunted then... Wait, Dragalge has Poison Point, so maybe... The first Night Slash was a Critical Hit and didn’t trigger Poison Point. I switched back to Duraludon and Night Slashe’s damage makes me sure the next one would KO, so I Dynamax and block a Night Slash. I expected Taunt on the second turn of Gigantamax, but they used Night Slash again and it would’ve KOed without Gigantamax. I switched back to Dragalge and got Crited again because of Weavile’s Scope Lens, but Poison Point Poisons and they can’t KO without another Crit. They used Taunt when I tried to Rest and I don’t know if they’ll use Triple Axel or Night Slash. I can’t afford to lose Appletun and he already has a worrying amount of damage. I’m pretty sure they’d use Night Slash, but I sacrificed Duraludon instead of letting Appletun take more damage. I sent Dragalge back in and try Rest. They use Night Slash again... and Crit again. Dragalge survived at 5 HP! Guess what the next two Night Slashes did. Critical Hits. The third one left Dragalge at 4 HP because it didn’t Crit, but don’t worry, the one after that did. Apparently, facing Weavile wasn’t enough bad luck. The AI must have thought it was weird that they weren’t using Taunt because they used it on their final turn before going down.
I needed something Appletun could switch into and I got kind of lucky with Whiscash.

I say kind of because could be bad after 6 Dragon Dances. Thankfully, Zen Headbutt didn’t deal that much more than half damage and didn’t cause flinches. I wasn’t sure how safe I was because Wishcash was the better Pokemon against Dragalge. Their last Pokemon might be good against Appletun.
The third Pokemon was Alakazam.

Between high power and the possibility of Magic Guard, this could suck. It used Reflect while I tried Leech Seed and nothing happened at the end of the turn... Crap. Magic Guard. Psychic was dealing a little less than half, but just when I thought I may be good, it lowered my Special Defense. It’s still barely doing more than half after the drop, so I may still be fine? Nope, that first one was just a low roll and the third Psychic after the drop lowered Special Defense again. I hope they’re out of Psychic PP and they use Shadow Ball. Okay, I know I keep tempting fate, but I think I’m good now for real... Oh, a Critical Hit. I want to complain, but it didn’t do enough to make me panic. Another Crit happened and it lowered Special Defense again. I switched to Dragalge and it lowered Dragalge’s Special Defense... Really? I was going to switch back either way, but really? Alakazam couldn’t do much without the Special Defense drops and Reflect and Safeguard gave plenty of time to have Dragalge heal and use the Leppa Berry to restore Appletun’s PP.
“Battle” 16 started with staring down death again. Salazzle...

and I had Protect go back to 10 PP against Alakazam instead of keeping it at 1 PP so I could protect the Leppa Berry from Corrosive Gas by eating it immediately... You’ve got to be kidding me. I used Protect to was a PP, but they used Acrobatics. That's interesting, but I still switched to Dragalge because they know and will use Corrosive Gas. After a little bit, I start thinking this isn't going to work. Corrosive Gas has 40 PP and I don’t think Dragalge had enough PP to outlast that and the rest of the moveset. It did try Acrobatics when Appletun used Protect on Turn 1, so maybe there’s a chance of keeping the berry? I have no choice but to try and... Corrosive Gas... I’m tempted to rage quit. It's not Poison losing on "Battle" 1 of the third leg yet again, so I spam Recycle instead. They used Disable the turn after Recycle ran out of PP. I'm not sure if the AI is being stupid or trying to rub salt in the wound. The only bright side is they can't do anything threatening other than Corrosive Gas.
I really hoped the next Pokemon would be one I’d lose to without Duraludon because I’d know I'd lose even if I didn't lose the Leppa Berry. Seaking

isn't that strong, but I'd forgotten it knows Drill Run and let Dragalge take a Super Effective hit. It didn't do more than half though and I could just switch to Appletun after that. Seaking's Bounce is a joke with Protect. Drednaw

was a slightly bigger threat. They used Dragon Tail to make me switch and I let Dragalge use Rest but she went down to 100/172 from another Dragon Tail. Poison Point activated, which helped save PP, and they spammed Skitter Smack against Appletun for the rest of the "battle," which was healed by Recover spam.
The start of “Battle” 17 was annoying because was easy and I had a death wish after losing the Leppa Berry. Crustle

would’ve been no problem with a Leppa Berry and I think it could let Dragalge wake up. Yep, Leech Seed outheals Heavy Slam. Bring on something I’d need Duraludon for! Tell me I would’ve lost either way! Ooh, Drampa!

That will do. Kill me you floppy neck chicken winged “dragon!” >:D And it has Sap sipper too. :D Now that I think about it, I should try to limp across the finish line and win this “battle” which means maybe I should’ve used Recover instead of Leech Seed. Dragalge got to use Toxic before fainting, so I’m going to Gigantamax and hope I can beat the last Pokemon with next to no HP. Judging by my PP though, I don’t think that’s happening. 2 Leech Seed, 4 Recover, and 2 Protect and 1/8 rounding down means... The last Pokemon is Stuntank? There might be a chance after all. Will it use Memento? Nope. Acid Spray takes out Appletun’s last 26 HP.
Disclaimer: I like Drampa and Yung Dramps, but I did try to taunt Drampa in a way that would make Yung Dramps mad at me.
Leg 3: 4 Wins. I'd say that's okay, but the third leg usually lasts the longest because I'm forced to limp on after losing Pokemon.
Total Streak Wins: 16
