Joker

”Joker” is an archetype used by Ace in Numbershot 1. Its members can substitute for an Xyz Material of a same-typed Xyz monster, but any other Xyz materials have to be the correct level. A notable feature of this archetype is that they always have something resembling a jester cap on their heads. Ace will exploit their Xyz Substitute effects with “Xyz Transformation” to use only the corresponding Joker to summon a powerful Xyz.
