Gardevoir @ Assault Vest
Ability: Trace
EVs: 252 SpA / 56 SpD / 200 Spe
Calm Nature
- Psychic
- Thunderbolt
- Shadow Ball
- Moonblast
So this could very well be a troll set (since I have less than 10 hours of playtime with this set in Gen 8 OU), but is very very fun to pull off. Assault Vest takes the already high 115 base SpD it has and with the 54 EVs this thing tanks like a chad (or chadette). Just to show that this takes a Specs STAB Shadow ball from Aegislash-Blade
252+ SpA Choice Specs Aegislash-Blade Shadow Ball vs. 0 HP / 56+ SpD Assault Vest Gardevoir: 234-276 (84.4 - 99.6%) -- guaranteed 2HKO
Psychic and Moonblast are STAB , with latter having a chance to decrease SpD and former SpA and hit hard neutrally as well, as for an example hitting a tank neutrally:
252 SpA Gardevoir Moonblast vs. 252 HP / 4 SpD Clefable: 165-195 (41.8 - 49.4%) -- guaranteed 3HKO after Leftovers recovery
Thunderbolt hits Water-/Flying- mons and can take a dump on some tanky mons very hard, without being Modest like:
252 SpA Gardevoir Thunderbolt vs. 40 HP / 252 SpD Alomomola: 238-282 (49.4 - 58.6%) -- 67.2% chance to 2HKO after Leftovers recovery
Shadow Ball is good coverage and well hits hard.
I am not at all a good player, as I started Pokemon this September only, with FireRed, but I am having fun using this set in Showdown for the entirety of 10 hrs I used it. Any suggestions and improvements are highly appriciated.
