until currently all our moon / shadow spells other then 3 have been changing our self into a target that would aid us. Perhaps a move for future moon spells could have a reverse effect on the enemy. This would force them into 5 turns of moves and 3 turns if its a chapter boss or 2 if it's a player in pvp. Examples:
Sheaponza: turns enemy into sheep 2 turns : gives them a deck of useless taunt cards + reduces reduces resist by 20%
Ribbiiitan: turns enemy into a frog giving them life mastery and healing but increase incoming damage to them by 100%
PaKaNesse: turns the enemy into a poodle increasing all taunt done by 400% but gives enemy + 10% resist.
