"Rank-Up-Magic" (ＲＵＭ（ランクアップマジック） Rankuappu Majikku) is an archetype of Spell Cards introduced in the Yu-Gi-Oh! ZEXAL anime. Their effects allow one to Rank-Up an Xyz Monster. An Xyz Monster with a Rank higher than the target is then Special Summoned from the Extra Deck, with the targeted Xyz Monster and its Xyz Materials both becoming Xyz Materials on the newly Summoned monster. This process is called either "Chaos Xyz Evolution" (when performed using Rank-Up-Magic cards that are associated with the power of Chaos) or "Rank-Up Xyz Evolution" (when performed using other methods).
