Overhyped deck
I understand how Mewtwo/Gardevoir deck works but most battles are down to your luck. 8/10 random fights I've had, I didn't manage to fully evolve a single Ralts and my entire gameplay was based on Giovanni, Sabrina, X Speed and Red Card. It's frustrating when you're down to 6 or even 5 cards and you still can't get one of two Ralts/Krila/Gardevoir that sit in your deck.
Sure, all them supporter cards give you time and help to build Mewtwo but if you're still missing one of Gardevoir evolutions for extra energy, you're likely doomed after single Psydrive. Unless you've managed to knock something out ahead of losing 2 energies with that 150 DMG blast.
Don't take me wrong, I still managed to win 7/10 of that battles, but it's not as enjoyable as I expected. All the planning ahead and predicting opponents' moves are clearly the best parts of this deck, but it involves too much luck/RNG to make it fun in long run.
It's also very difficult deck to work with if you're out of luck with Gardevoir/Supporters while facing Misty, Pikachu EX or Koga decks. They can cause heavy damage to you in no time and if you have bad hand, you're likely to lose.
As for the author of this deck, you should include some strategy for players who don't have great understanding of its mechanics. The link in description doesn't provide such information.
