Plasma Summon

A Plasma Summon (プラズマ召(しょう)喚(かん), Purazuma Shoukan is the method of Summoning a Plasma Monster. To Plasma Summon, you have to have 2 or more Xyz Monsters on your side of the field with the same Rank, by sending those Xyz Monsters to the Graveyard. The Xyz Materials that those Xyz Monsters had before becoming Plasma Materials are also "attached" to the Plasma Monster, but like Hybrid Monsters, they do not play a particular role, such as using them or "detaching" them. This is a Plasma Summon.

You can use Monsters that can be treated as Xyz Monsters as Plasma Materials, but their Level must be treated as a Rank instead.
