I haven't bought any DLCs in awhile (I didn't even buy the Joker DLC!!!) but after playing against several Hero players, I must honestly say he's not that impressive. His basic attacks are too much like BotW Link's, and while his neutral and side specials are powerful, they can be easily avoided. I thought only the person using Hero would be seeing the command window, but it looks like I was wrong. Also you can't activate a spell immediately, so more often than not I get a good attack in while they're still deciding on what spell to use. His recovery is good, but could also be gimped. Plus, if you use too much mana and run out of it, a simple backthrow is enough to kill you, since they don't have enough mana to do their up B.
