Something through a little testing has proven to be a potential dark horse is Mega-Gallade. Through its ridiculous Attack, good speed, decent movepool and immunity to Flinches, it carves out a great niche against Mega-Kangaskhan and generally hits hard throughout a battle. I have opted for a more bulky spread which grants Gallade a lot of staying power compared to a standard 252/252 spread.
Gallade (M) @ Galladite
Ability: Justified
EVs: 252 HP / 12 Atk / 52 Def / 192 Spe
Jolly Nature
- Close Combat
- Ice Punch
- Rock Slide/Zen Headbutt
- Protect
With this spread Mega-Gallade outspeeds everything from Garchomp downwards (so base 102's), the 12 Attack EVs ensure the OHKO on most builds (covers up to 252 HP sets) Mega-Kangaskhan with Close Combat, also securing the OHKO on Landorus-T (2HKO after Intimidate). The HP and Defence EVs allow me to survive a Double-Edge from Kangaskhan (useful if they are under Tailwind) Rock Slide is the third move, mainly for the Charizard's and potential Talonflame switch ins. Zen Headbutt can be used for Mega-Venusaur. Protect is used to guarantee the Mega Evolution, and seen as this is VGC, it is weird not to use Protect. There were some other calcs that influenced the spread, but I can't remember them for the life of me.
