Forest of Vitality
Stadium Trainer
Each player's Grass Pokémon can evolve into Grass Pokémon during the turn they play those Pokémon, except during their first turn.
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.
