>>9704325MitB cash in on a face champion, doesn't matter which belt, actually the tag or a midcard would be perfect so people can be butthurt over him "wasting" the briefcase. Or win King of the Ring so he can start unironically calling himself "the real Rey Mysterio"
But if you wanna give him final boss of the IWC level heat, he needs to interfere in Cody's rematch with Roman, and cost Cody the shot by just nailing him in the dick. Preferably in a match where the Bloodline has been banned from ringside.
