2+ Level 4 monsters Once per Chain (Quick Effect): You can detach 3 materials from this card; Special Summon from your Extra Deck, 1 Xyz Monster that is 1 Rank higher than this card, except a "Number" monster, by using this face-up card you control as material. (This is treated as an Xyz Summon. Transfer its materials to the Summoned monster.) You can detach 7 materials from this card; skip your opponent's next turn. Once per turn, during the End Phase: You can attach 1 "Stellarknight" card from your Extra Deck to this card as material.
