Ultima Cards, while placed on the field like monsters, are not considered to be actual monsters. As such, they are unaffected by cards/card effects that state "monster" in their card texts. However, they can still be destroyed, targeted, and effected by cards/card effects that only specify "cards" (ex: An Ultima Card cannot be destroyed by the effects of, as it is not a monster, but it can be destroyed by , as it still a card).
Ultima Cards do not have Levels. Instead, they have Hierarchies.
