The Phantom Knights' Rank-Up-Magic Requiem

Target 1 "The Phantom Knights" or "Xyz Dragon" monster in your GY or banishment; Special Summon it (but negate its effects), then Special Summon from your Extra Deck, 1 "The Phantom Knights" or "Xyz Dragon" Xyz Monster that is 1 Rank higher than a DARK Xyz Monster you control, by using that monster as material (this is treated as an Xyz Summon, transfer its materials). You can only activate 1 "The Phantom Knights' Rank-Up-Magic Requiem" per turn.
