2 Level 4 monsters This card gains 300 ATK for each Xyz Material attached to this card. Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up monster you control; change that face-up monster to face-down Defense Position, and if you do, during the End Phase of this turn, change it to face-up Attack Position.
While it's cool that Wind-ups are getting more cards, unfortunately I don't see this one seeing much play. The flipping effect let's you re-use your wind-up effects (Warrior, Magician, Rat, etc....) but then they have to survive your opponents turn. You're better off using your monsters for different rank 4's like malevolent sin
