You may play only 1 Stadium card during your turn. Put it next to the Active Spot, and discard it if another Stadium comes into play. A Stadium with the same name can't be played.

Once during each player's turn, that player may search their deck for a Basic Pokémon that doesn't have a Rule Box and put it onto their Bench. Then, that player shuffles their deck. (Pokémon ex, Pokémon V, etc. have Rule Boxes.)
