Rank-Down (ランクダウン Rankudaun) is a method used to Summon lower-Rank Xyz Monsters in the Yu-Gi-Oh! ZEXAL anime. A variant of Xyz Evolution, it was first seen in the Duel between Eliphas and Yuma Tsukumo, who used "Rank-Down-Magic Numeron Fall" to Rank Down "Number 39: Utopia" into "Number 39: Utopia Roots". Later, Astral used "Rank-Down-Magic Utopia Fall" to Summon "Utopia Roots" in his Duel against Yuma.
