Sorry for double post, just wanna get this one out of the way. Presenting...
Egg Salad Two: Alolan Boogaloo
Alolan Exeggutor
Type: Grass/Dragon
Stats: 95/105/85/125/75/45 (BST: 530)
Abilities: Frisk/Harvest (HA)
Notable Moves: Dragon Hammer, Earthquake, Wood Hammer, Sludge Bomb, Psychic, Psyshock, Leaf Storm, Draco Meteor, Flamethrower, etc.
Main Goal: In contrast to its regular counterpart, make Alolan Exeggutor a better Mixed Sweeper (leaning towards Physical attacking) that doesn't need to rely on other Pokemon's assistance, i.e. weather.
Analysis
Stats and Typing: Tall Egg (referring it as this for the whole analysis) has an interesting typing. It's weak to 6 types (x4 weak to Ice) and resists 4 types. It isn't as dire as Regular Egg's weaknesses, as Tall Egg tends to lend much more towards the offensive. Offensively, Tall Egg's typing is fairly good; Dragon is always a good offensive typing to have. However, its horrid 45 Speed holds it down for any strong super effective move to blow it back. It also has a lot more Physical attacks that Regular Egg can't use, such as Dragon Hammer and the oh-so-powerful Earthquake.
NEW STATS: 95/125(+20)
/85/95(-30)
/65(-10)
/65(+20) (BST: 530)
These stats set apart Tall Egg from Regular Egg enough instead taking 10 base stat from Speed and giving it to Attack. Funnily enough, he become faster than Regular Egg. The Speed stat can be flexible, everything can't be fast, however I took some stats and put it to Attack to separate it from Regular Egg while also still being a decent Mixed Attacker with a respectable 95 Attack. Again, these stats are super flexible, always open to suggestions. These stats also allow him to have a respectable Speed to run Choice Band or Choice Scarf.
Abilities: Tall Eggs abilities are super mediocre. Frisk overall is a very subpar ability; many items are shown almost at the get-go, examples would be Leftovers, Life Orb, and Mega Stones. Harvest is a decent ability, but Regular Egg uses it better. In my opinion the best way to go about this is either only add one extra ability or add two abilities, replacing Frisk for one. These are some options I think will work best:
Reckless/Rock Head: These are grouped together due to have an equal amount of synergy with Dragon Hammer. However with that logic you may as well give Reckless and/or Rock Head to every Pokemon with Flare Blitz, Double Edge, etc.
Skill Link: This is the one I'm the most interested in. It feel Tall Egg flavor-wise but can be great competitively. It already gets Bullet Seed and Barrage, and Rock Blast couldn't hurt, no?
Adaptability: A great ability flavor-wise (adapted to Alolan environment) and competitively, however it's extremely powerful a point where it can't just be thrown around. This could be even more unlikely than Reckless or Rock Head.
Long Reach: A less powerful ability than the ones listed, however it can still have its uses. It's especially useful for avoiding things like Static, Poison Touch, and the like.
Nueroforce: fuck you lol
Moves: Tall Egg's moves are already great, it was honestly just his Speed really holding it back, but a little change couldn't hurt.
Rock Blast: This will only be useful if Skill Link is the ability chosen. It's basically there to give him more options when using Skill Link.
Leaf Blade: This opens an options to use a less powerful move than Wood Hammer without the recoil.
Nothing really else to add, Tall Egg's movepool is already pretty good, no need for a major overhaul.
Example Set:
tall egg monkaS (Exeggutor-Alola) @ Choice Scarf
Ability: Long Reach or Adaptability
EVs: 252 Atk / 4 SpA / 252 Spd
IVs: 0 Spe
Naive/Hasty Nature
-Dragon Hammer
-Earthquake
-Wood Hammer
-Draco Meteor/Flamethrower/Filler
Not much to say here, EVs and Nature for Speed plus Scarf allows Tall Egg to be a sort of Revenge Killer or late game Sweeper for clean up.
Again, sorry to double post, but I really wanted this to go out. Cheers!
