Retreat cost

A retreat cost (Japanese: にげる retreat) is the number of TCG Energy attached to a Pokémon that must be discarded in order to retreat to the Bench and bring up a Pokémon from the Bench. Retreat costs printed on a card range from 0 energy (often called a "free retreat") all the way up to 5 energy. They are marked by TCG Colorless Energy symbols. A player may only retreat once per turn.
