This card in your Hand/Trash can be summoned without paying the cost when your "Evol"-named Spirit is either summoned or switched onto the field from the Hand. This effect does not stack.
[LV1][LV2][LV3] (When Summoned) Draw two cards.
[LV2][LV3] (Your Attack Step) When this Spirit or your "Evol"-named Spirit attacks, the opponent can't block unless they destroy a Spirit they control.
