Deafening Spirit- 1/4 Orange Enhancement: Negate and discard the last Good Enhancement played in battle. You may treat this card as an Evil Character until the end of this battle.
Deafening Spirit is an Enhancement, but it treats itself as an Evil Character the moment it is played. Once it is played, can it be interrupted or negated by a card that interrupts/negates Enhancements, a card that interrupts/negates Characters, or both? Would a "Negate Characters." ability already in play not apply to it because it entered play as an Enhancement and only became a Character afterwards?
