Dream Mirror Fantasy (RIRA-EN091) - Rising Rampage 1st Edition

If you control a "Dream Mirror" monster: Target 1 each of your banished "Dream Mirror of Joy" and "Dream Mirror of Terror"; shuffle them into the Deck, and if you do, banish 1 card on the field. If a "Dream Mirror" card(s) you control would be destroyed by battle or card effect, you can banish this card from your GY instead. You can only activate 1 "Dream Mirror Fantasy" per turn.
