Xyz Material Counter

An Xyz Material Counter (エクシーズ素材カウンター Ekushīzu Sozai Kauntā) is a used for Fusion Monsters that state at least 1 Xyz Monster as a Fusion Material. Xyz Material Counters are, as their name implies, a substitute for Xyz Materials, as actual Xyz Materials can only be attached to Xyz Monsters. Xyz Material Counters can be removed or added to a suitable Fusion Monster with card effects or to activate their own effects in order to replicate an Xyz Monster's playstyle.

Fusion Monsters that use Xyz Material Counters always have the following statement in their lore: "When this card is Fusion Summoned: Place 1 Xyz Material Counter on this card for each Xyz Material that was attached to an Xyz Monster used as a Fusion Material Monster for this card. If a card effect that would involve detaching 1 or more Xyz Materials would affect this card: You can remove an equal number of Xyz Material Counters from this card instead."

In the anime, Xyz Material Counters are instead actual Xyz Materials, breaking conventional rules by having Xyz Materials attached to a Fusion Monster.

Currently, the only monster that uses Xyz Material Counters is "Wizard Knight Magi-Senshi".
