My Mega Gardevoir Deck (Improvement)
 
            Hi guys,
So, below I put the deck I'm using right now for the Pokémon TCG Live ladder. I want to use Hilda or Lillie's Determination, but I'm not sure what to modify. Honestly, the deck is pretty solid; it's basically the Gardevoir Ex with some slight changes. I ranked from Garedos Ladder to Mewtwo in a day.
Honestly, it doesn't do great against any dark type, but mostly it sustains. 
It would be great if you could give me some tips!
