It's not easily done
The aim of this deck is to get Mew ex or Mewtwo ex out as quickly as possible and start pouring Energy into them, using Jynx and the Ralts line to screen until Gardevoir comes out
You wont always be able to do something with that mana, especially in the late game, but it isnt unreasonable to think this will let you play a more powerful card or more cards the turn after you play it, and having that tacked on to a relevant body makes for a nice card I think youll want one of these in most Green decks
With Drakloak and Xatu helping you draw more cards, and Tatsugiri jumping into the Active Spot early to fish out your best Supporters, this deck keeps things flowing
Ironically, this massive popularity probably prevented the card from seeing more play in tournaments, as players who might have tried to reach for the Queen instead decided to cash them in for other cards they needed more
The reasoning for this massive hype, was the fact that this deck gained two insanely powerful additions, Skewer the Critics and Light up the Stage
