Stadium
Each Special Energy attached to a Pokemon in play provides [C] Energy and has no other effect.
This Stadium stays in play when you play it. Discard it if another Stadium comes into play. If a Stadium with the same name is in play, you can’t play this card.
Mew could probably run a copy of this, but it might end up in your turn 1 hand and block meloetta. This stadium might kill decks like zoroark, malamar, or mad party that have less space for counter stadiums.
