Xyz Material

Exceed Material Monsters (エクシーズ素材, Ekushīzu sozai) are the result of monsters being used in an Exceed Summon. When an Exceed Monster is summoned, the monsters used in the Exceed Summon are placed underneath the monster instead of being sent to the Graveyard. These monsters may be used for a card effect, such as the effect of "No. 17, Revise Dragon".
