If a player uses Venomoth's "Dizzying Wind" attack and the opponent tries to play a Stadium during their following turn and flips tails, will they have used up their Stadium for the turn? And what happens to a Stadium already in play, does it get discarded or not?
If the opponent flips tails that card is discarded and doesn't count as being played, so they can still attempt to play another Stadium. The existing Stadium would remain in play.
