Special Summon 1 Spellcaster monster with 1500 DEF from your hand or GY in Attack Position or face-down Defense Position, then, if you control monsters with 2 or more different Attributes, you can destroy 1 face-up card on the field. You can banish this card from your GY, then target 1 "Possessed" Continuous Spell/Trap in your GY; place it face-up on your field. You can only use 1 "Possessed Partnerships" effect per turn, and only once that turn.
