Even though this isn't a complete list, I gotta say that Jumpluff and Crobat realistically don't cut it in this format. As techs for Mew, they're alright, but your Mew line isn't bulky enough to support what it's trying to do. Cleffa is borderline, because it's prone to sniping at this point. I would say that given this list right now, Yanmega is fine, Mew is fine, you should probably just run 1-2 Crobat Primes on their own for the tech, and then fill out your Jumpluff lines. Realistically with this you should set your stragety up for: Mew prime sending 1 Jumpluff to the lost zone, then fill out the bench with hoppips, start candying up the Jumpluffs while holding off with some Mew Primes, keep a full bench and mass attack to victory.
