Sunny Castform (ex5-26) is a Fire-type Basic Pokémon from the Hidden Legends expansion with the Temperamental Weather Poké-Power. Its Poké-Power lets you swap it for another Castform form from your deck once per turn, and its Sunburn attack can Burn the Defending Pokémon if the Stadium High Pressure System is in play. The card also provides utility by retrieving a Stadium card from your discard pile with Sunshine, supporting stadium-based strategies.
