3 - Chaotic Swell This Stadium goes into this position because besides being a card that plays in Mewtwo & Mew-GX UNM 71 decks precisely to be an answer against Silent Lab PRC 140, it also doesn't affect your ability of copying EX and GX Pokmon attacks from the discard pile, being an essential card for this strategy
