A question of my own: Is there a pokemon that can be used as a check talonflame, mega aerodactyl and mega gengar in a sunny day team? i am thinking hippowdon (tanky + rockslide/slack off for talonflame and mega aero, whirlwind/roar for mega gengar) but is it worth running it in a sunny day team?
It's gonna be hard finding something that can check two strong physical attackers and something with a base 170 attack single-handedly, and also I'm not sure what your team's like, but here's an option:
Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 248 HP / 192 Def / 68 SAtk
Bold Nature
IVs: 0 Atk / 29 Spd
- Volt Switch / Thunderbolt (lol)
- Pain Split
- Will-O-Wisp
- Hydro Pump
Outside of sun, HPump has enough power to OHKO both Talonflame and Mega-Aerodactyl. This Washtom isn't 2HKO'ed by Jolly Mega Aero's Stone Miss and laughs at anything Talonflame throws at it. 29 IVs in speed are to get the switch advantage against opposing Washtoms running 30 IVs if you're into that, I guess you can call it negative speed creep lol. Wisp renders Mega Aero useless for the rest of the game, and also allows Washtom to comfortably check Aegislash, another really prominent 'Mon. It'd take too many EVs to guarantee survival from 2 Sludge Bombs from Mega Gengar, and there's that 30% poison chance to consider as well.
Alternatively, Tbolt can cleanly OHKO Talonflame without SR in the Sun OHKO Mega Aero with SR; Volt Switch manages clean 2HKOs on both though.
Also, a spread of 192 HP / 248 Def / 68 SAtk Bold gives you that nice Lefties number, and you'll only have a 8% chance of being 2HKOed by Mega Aero after SR (the other spread is a 5% chance after SR).
All in all, a pretty solid bulky pivot and physical attacker check though.
Mega Aggron shrugs off Talonflame and Aerodactyl, and can take on Gengar with Earthquake, but I'm not sure if you've already got a Mega on your team.
EDIT:
Ixsiehn no problem, glad to have helped :]
