Ancient Crystal (sm5-118) is a Trainer — Pokémon Tool card from the Ultra Prism expansion. When attached to Regirock, Regice, Registeel, or Regigigas, it reduces damage those Pokémon take from opponent attacks by 30 (after Weakness and Resistance). It also allows you to play any number of Item cards during your turn while it's in effect, enabling more Item-driven turns.
