Crystal Miracle

When a Spell/Trap Card, or monster effect, is activated: Destroy 1 "Crystal Beast" card you control, and if you do, negate the activation, and if you do that, destroy that card. If a "Crystal Beast" card(s) is placed in your Spell & Trap Zone while this card is in your GY (even during the Damage Step): You can banish this card; place 1 "Crystal Beast" monster from your hand, Deck, or GY face-up in your Spell & Trap Zone as a Continuous Spell. You can only use this effect of "Crystal Miracle" once per turn.
