Rank-Up-Magic Skip Force

Spell Normal

(1) Target 1 “Raidraptor” Xyz Monster you control; Special Summon from your Extra Deck, 1 “Raidraptor” monster that is 2 Ranks higher than that target, by using that target as the Xyz Material. (This Special Summon is treated as an Xyz Summon. Attached Xyz Materials also become Xyz Materials on the Summoned monster.)

(2) During your turn, except during the turn this card was sent to the Graveyard: You can banish both this card and 1 “Raidraptor” monster from your Graveyard, then target 1 “Raidraptor” Xyz Monster in your Graveyard; Special Summon that monster.
