I actually made a HC for Jaraxxus a while ago (and a few for some OW hereos, but those aren’t relevant for my point here), but I recently read a reply to a post where someone suggested that it could be Fizzlebang who summons Jaraxxus who then kills him as a heroic ability, and then gets to wreck havok untill he respawns, which to be honest almost is too good of an oppertunity to pass up on. Anyway, do you mind taking a look at him?
