so what do you all think of this team?

 

[Nah]

Bulky attacker Rotom-W needs HP and Speed more than its defenses and Sp.Attack. A better EV spread is 232 HP, 56 Sp.Attack, 220 Speed. It also doesn't need any other attacks outside of its STABs and Hidden Power. Will-o-Wisp is a nice option to screw with physical attackers and help keep it alive.


Façade is tempting to use on a Breloom with Poison Heal, but your current set-up leaves it walled by Ghosts. So swap Façade with something like Bullet Seed or Rock Tomb.


Scizor has plenty of power after a Swords Dance boost, so all those attack EVs isn't necessary. It's also best not to have 2 Pokémon hold mega stones on the same team. Especially when one is Charizard, who needs to be in its mega form in OU. You'll wanna use this for a bulky dance Scizor:


-Scizor w/Leftovers
Nature: Adamant
Ability: Technician
EVs: 252 HP, 40 Attack, 212 Sp.Defense
Moves: Swords Dance, Roost, Bullet Punch, U-turn/X-Scissor/Bug Bite


You can also use one of these sets too:


-Scizor w/Life Orb
Nature: Adamant
Ability: Technician
EVs: 252 Attack, 252 Speed, 4 HP
Moves: Swords Dance, Bullet Punch, Brick Break/Superpower, X-Scissor/Bug Bite


-Scizor w/Choice Band
Nature: Adamant
ability: Technician
EVs: 252 HP, 252 Attack, 4 Speed
Moves: U-turn, Bullet Punch, Superpower, X-Scissor


Also, what's with the IVs on it?


Hydreigon prefers Flash Cannon over Surf so it can at least do something against Fairies. Since you're using a Choice set, Draco Meteor is better than Dragon Pulse for the raw power. You use it in a hit and run fashion.


I think it'd be better to use Mega Charizard X on your team instead of Y. Forretress and Scizor hate fire attacks, and the Sun MegaZard Y brings makes that worse, not to mention it weakens Rotom's Hydro Pump and doesn't do anything for the team. MegaZard X resists Fire attacks even better and doesn't bring the sun.


-Charizard w/Charizardite X
Nature: Adamant/Jolly
Ability: Tough claws
EVs: 252 Attack, 252 Speed, 4 HP
Moves: Dragon Dance, Flare Blitz, Dragon Claw, Earthquake
