lol, love the sprites. This team is very good, and there is little I can add, but I will offer some suggestions.
This guy is great, but you could have him as more of a mixed attacker, with this moveset:
His Attack is great, and his SpAttack is Ok, so you can mix him if you like
This guy is perfect, IMO, because he can cover his weaknesses and recover.
I see you're going for a stall Mew. Fine with me, but you can also have Toxic or T-Wave instead of Will-O-Wisp
Good, but you can also add Synthesis to gain health.
Fine, but if someone Taunts and then Torments you, you'll start Struggling(although I don't who would do that).
Perfect! I would hate having to fight this guy
Again, this is a great team with little to add, all I can do is a give you my opinion.
