Rank-Up-Magic

"Rank-Up-Magic" ( Rankuappu Majikku) is an archetype of Spell Cards from 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 Special Summoned from the Extra Deck, and the targeted Xyz Monster and its Xyz Materials become Xyz Materials on the newly Summoned monster. This process is called "Chaos Xyz Evolution" (when performed with Barian, Numeron, or Argent Chaos Force) or "Rank-Up Xyz Evolution" (when performed by Astral Force).

The Rank-Up spells were first introduced in the anime by Girag who used it continuously on students from Heartland in order to take the Numbers from Yuma, Astral and Shark. Each time it would be used to Rank-Up Xyz monsters into CXyz monsters in order to overpower the Numbers.

Mizar used it next when he himself ranked up his Number 107: Galaxy-Eyes Tachyon Dragon in order to form it's chaos form. This monster wasn't seen on this encounter.

Alito and Girag both ranked up their respective Number 10X monsters. Both of them were defeated by Yuma and Astral (Girag was also defeated by Rei posing as Vector).

Yuma gained his own Rank-Up spell in the form of Rank-Up-Magic Limited Barian's Force during his duel with Girag from "Ray" but was later transformed into it's true form of Rank-Up-Magic Numeron Force by ZEXAL II.

Vector also demonstrated his mastery of Rank-Up Spells when he used Rank-Up-Magic Barian's Force on his Number 10X number but also to brainwash Umimi.

When Yuma went to the Astral World looking for Astral he dueled against Eliphas who used Rank-Up-Magic Astral Force in his duel against Yuma.

Quattro, Trey and Quinton also demonstrated the ability to Rank-Up their monsters with the spell card Rank-Up-Magic Argent Chaos Force when dueling the Barians.

When Shark became Nasch once again he augmented the Barian Emperors with the spell card Rank-Up-Magic The Seventh One which worked specifically for their Number 10X monsters and was used by all the Emperors save Vector.
