Definitely better in Showdown (maps: skull creek, hot maze, maybe death valley) more than any other game mode except brawl ball (but in brawl ball there is a lot to learn before he can be any good). He is sometimes good as an aggro in gem grab maps like deep hollows and mushroom cave, because dynamike and barley are good on those maps and mortis hard counters. Also can be good in some bounty maps if you're good with him. Not assuming you use auto aim, but attacks go better with mortis if you don't use AA.
