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.

Whenever a Colorless Pokémon (yours or your opponent's) is Knocked Out by damage from an attack from the opponent's Pokémon, that player takes 1 fewer Prize card.

You cannot play this card by itself. You must combine 2 different Legendary Summit from your hand to play as 1 Stadium card.
