Gingerbread Man
I was just thinking with all the Christmas themed champions the next logical step would be Gingerbread Man! He could be an epic or legendary speed champion, of course. :-) I would like to see a strong All Battles speed aura, multi-hit A1 with a chance to reduce turn meter on each hit, AOE increase speed on his A2 and a passive that increases his speed by a few points whenever an enemy's speed is increased. For some reason Banner Lords seems like the right faction for me but if he was naughty maybe Knights Revenant.
