What do you think of this team?
Charzard
Metagross
Tyranitar
Blissey
Gengar
Lucario
Pretty much OU pokemon... All level 100. Should I change any pokemon?
i would replace lucario and maybe charzard, depending on how you use him. For an OU to replace him i would use a bulky gyrados, if you want a uu try a sub-seeder sceptile.
Charizard loses 50% of its health when it switches into Stealth Rocks. That gives you a max of 4 times in(Lead, 2 SR damage, and 1 time at 1HP. That also assumes you aren't damaged by anything else, and if Tyranitar goes in you'll probably get Sandstorm Damage).
And please (this should be a rule) if you post a RMT have explanations for the purposes of each pokemon, as well as the EV spread, Nature, Item and Moveset.
@. :I'm pretty sure this is an OU team(other than Zard).
