Theorealize #DUAD-EN055

SPELLSpell

Send 1 "Medius the Pure" from your Deck to the GY; look at the top card of your opponent's Deck, and place it on the top or bottom of the Deck. You can banish this card from your GY, then target 1 face-up monster you control and declare 1 Monster Type and 1 Attribute; that monster becomes that Type and Attribute, until the end of your opponent's turn. You can only use each effect of "Theorealize" once per turn.
