If they messed up Gardevoir GX then it would have been a Tier 0 deck. Gardevoir isn't a broken deck. And with all honesty it's just one card not an entire archetype. Metal has every possible energy acceleration now: Energy from Discard Pile, unlimited from Hand AND from deck AND nerf-Max Elixir into a card. Lastly, take a closer look into the tops of the last 7 major tournaments so far and the representation of Gardevoir in the Top 8. Among the hilariously small representation in the top 8, you'll also notice a that Gardevoir isn't a deck that wins because of the deck itself but from the people that pilot it. And just this fact alone: this deck doesn't win you any tournament (in comparison to other TCGs like Yugioh) is a great achievement of the Pokemon Company.
All of that is wrong.
Evolutions??! Eeww!! That is the most trashiest and last XY set that we have. Better SM-on
That wasn't my point but okay.
