Stat-wise, yes. However, Mewtwo-A's coverage over Lugia (namely, Rock Slide and Dynamic Punch) give it an edge for the higher PvP Leagues if you're into that sort of thing. It's still pretty shit.Isn't this thing strictly worse than Lugia?
As a non PvPer, the most interesting additions here are Wing Attack Moltres for pure Flying sets with the event exclusive Sky Attack, and Charm for Gardevoir so it becomes a top counter to things like Fighting-types and Dark-types. Togekiss and Granbull shouldn't be far behind either.
