Target 1 Rank 4 or lower Xyz Monster in your GY; Special Summon it. Its Attribute becomes WATER. You can banish this card from your GY, then target 1 WATER Xyz Monster you control; Special Summon from your Extra Deck, 1 WATER Xyz Monster that is 1 Rank higher than that monster you control, by using it as material. (This is treated as an Xyz Summon. Transfer its materials to the Summoned monster.) You can only use 1 "Xyz Revive Splash" effect per turn, and only once that turn.
