Chansey Seismic Toss vs. 244 HP Gliscor: 100-100 (28.4 - 28.4%) -- guaranteed 6HKO after Poison Heal
0 Atk Gliscor Earthquake vs. 248 HP / 252+ Def Chansey: 204-241 (29 - 34.2%) -- 3.4% chance to 3HKO
It cant even 5hko and you can absolutely abuse it for momentum, chip, defog, whatever. If running rocks on your gliscor you can set that up, and if you're running a swords dance set even you can set up in its face
Hawlucha @ Electric Seed / Grassy Seed
Ability: Unburden
EVs: 96 HP / 252 Atk / 36 SpD / 124 Spe
Adamant Nature
- Swords Dance
- Close Combat
- Acrobatics
- Substitute
Hawlucha simply uses Chansey as setup fodder due to Toxic and Thunder Wave immunity behind Substitute. After a Swords Dance or two, you OHKO and begin your potential sweep if you've already activated the designated seed.

Sableye-Mega @ Sablenite
Ability: Magic Bounce
EVs: 248 HP / 132 SpD / 128 Spe
Calm Nature
IVs: 0 Atk
- Calm Mind
- Dark Pulse
- Recover
- Psychic
The combination of magic bounce and seismic toss immunity means that chansey is quite literally useless against mega sableye unless it's going back to older gens and throwing ice beam into it's moveslots, which it can't really sacrifice something for nowadays, due to the insane amount of utility the other moves provide. The given spread outspeeds reuniclus(or in other words,toxapex that invests 4 speed evs), has the highest chance of surviving 2 heatran's magma storm with stealth rocks up while having the highest physical bulk.
+6 0 SpA Sableye-Mega Dark Pulse vs. 248 HP / 8 SpD Eviolite Chansey: 190-225 (27 - 32%) -- 64.3% chance to 3HKO after Stealth Rock
+6 0 SpA Sableye-Mega Dark Pulse vs. -1 248 HP / 8 SpD Eviolite Chansey: 288-339 (40.9 - 48.2%) -- 66% chance to 2HKO after Stealth Rock
no way we are not getting any spdef drops or flinches after throwing out so many psychics right?

Gengar is immune to toss toxic etc. You come in click sub and abuse this as fodder.
If he stays in bost 2 times and
+4 252 SpA Gengar Focus Blast vs. 248 HP / 8 SpD Eviolite Chansey: 498-586 (70.8 - 83.3%) -- guaranteed 2HKO
Could be fighting z but its a waste to click the the z vs a mon that can touch you anyways. Gost z is just better overall

Counter: Reuniclus /
Reuniclus @ Electrium Z / Fightinium Z
Ability: Magic Guard
EVs: 252 HP / 212 Def / 44 Spe
Bold Nature
IVs: 0 Atk
- Calm Mind
- Psyshock
- Recover
- Thunder / Focus Blast
Draco Meteor is a very uncommon choice, which leaves thunder up next as the strongest move the male of the eon twins could throw out on reuniclus.
252 SpA Latios-Mega Thunder vs. 252 HP / 0 SpD Reuniclus: 160-189 (37.7 - 44.5%) -- guaranteed 3HKO
252 SpA Latios-Mega Thunder vs. +1 252 HP / 0 SpD Reuniclus: 107-127 (25.2 - 29.9%) -- guaranteed 4HKO
The most we need are 3 recovers and we can start to set up calm minds on mega latios and start the snowball effect. Besides, consistently landing high roll thunders and having a para and it activating is quite an unlikely case, and should that happen we can just find an opportunity later and try again
