Judge Judge no mi...
I think that'll be pretty cool, you get to do cool lawyer things and shit.
Plus you get to wield a massive hammer, like Thor.
Death penalty - you get to throw guillotines, lethal injections and rope at your opponent to kill them
Imprisonment - summon a giant cage from up above to trap your enemy
Subpoenas - you get to summon a giant penis to join you in battle.
Under Oath - force your opponent to tell the truth... y'know, like wonder woman's whip thing.
This Case is Adjourned - releases your enemy from oaths and imprisonment.
Bench - throw a massive bench at your enemy to punish him for being a dick.
Order - Idk, it's just you hitting your enemy repeatedly with your hammer and shouting ORDER!!
Awakening - you get to make your own laws to restrict the battlefield. Is your enemy a sword user? Then proclaim "NO SWORDS!!".. Is your enemy a DF user? Then proclaim "NO DF's!!".. If your opponent goes against your law, they get indicted, paralyzed, and sentenced to a punishment of your choice.
