Legendary Ocean Trench(伝説の海溝)

When a Pokemon in play is healed (both yours or your opponent's), double the amount of damage healed.

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.

You can only put this card into play from your hand with the other half of Legendary Ocean Trench, and it counts as one Stadium card while in play.
