Sunny Castform (ex5-26 Reverse Holofoil) is a Fire-type Basic Pokémon from the Hidden Legends set with the Poké-Power Temperamental Weather. Its Poké-Power lets you search your deck for a Castform form (Castform, Rain Castform, or Snow-cloud Castform) and switch it with Sunny Castform once during your turn, shuffling Sunny Castform back into your deck. It also has the attack Sunburn which deals 40 damage and can Burn the Defending Pokémon if High Pressure System is in play, giving it a niche offensive interaction.
