Boost Energy (Reverse Holofoil)

Description

Boost Energy (ex10-98 Reverse Holofoil) is a Special Energy from the Unseen Forces set that was printed as card 98/115. It can only be attached to an Evolved Pokémon, provides three Colorless Energy while attached, and must be discarded at the end of the turn it was attached or immediately if attached to a non-Evolved Pokémon. The Pokémon holding it cannot retreat while Boost Energy is attached, creating a trade-off between heavy colorless energy acceleration and loss of mobility.
