The baseline of a 5 mana 4/4 trample is too inefficient and the madness cost is manageable with free outlets but makes it relatively difficult to use with things like Faithless Looting, Fauna Shaman or more expensive discard effects
You spend your picks on bombs, removal, card advantage, and mana fixing and simply overpower opponents when the games go long
