δ Rainbow Energy (Reverse Holofoil)

Description

δ Rainbow Energy (ex13-98 Reverse Holofoil) is a Special Energy card from the Holon Phantoms set. While attached to a Pokémon with the δ symbol it can provide any type of Energy but only supplies one Energy at a time; otherwise it provides Colorless Energy. As a Special Energy, it is used to meet attack costs and can influence deck strategy by enabling type-flexible requirements for Delta Species Pokémon.
