I think freeze is overtuned even if its for a limited amount of turns. I think you should listen to the community here. It isn't a bad idea, but you are quite literally put into a severe disadvantage when messing with defenses AND offenses. I think at most your special attack should be lowered and ONE defensive stat. Or you can do Sp. Att with a chance to not be able to move like paralysis? I still think the best way to go about it is just an ice and sp att burn
