Rank-Down-Magic

"Rank-Down-Magic" (ＲＵＭランクアップマジック Ranku Daun Majikku) is an archetype of Spell Cards that are opposites of the Rank-Up-Magic cards. Their effects allow one to Rank-Down an Xyz Monster. An Xyz Monster with a Rank lower than the target is Special Summoned from the Extra Deck, and the targeted Xyz Monster and its Xyz Materials become Xyz Materials on the newly Summoned monster.
