Gardevoir/Gothitelle/whatever you think the last G is can still work, and does. But it also runs Mewtwo. The only decks that run Mewtwo heavily are big basic decks that are greatly hurt by trainerlock and you run Mewtwos as revenge killers.
Like Cinema said, it's a soft counter. It handles it really well but obviously not as well as Mewtwo does.
