It won't work...Smiter's wording is if an opponent would make you discard, not yourself.

I made a deck similar to this one. Couple of things for consideration: Run Bloodstained Mires and Blood Crypts. Enchantments (Leyline of the Void, Rest in Peace) will mess up your deck pretty good. Consider splashing some green for golgari charm or something of the like. Also try fiery Temper and Brain Gorgers. The madness mechanic is fun with decks like these.
Thanks ??
Theyre going to be in the sideboard once i get around to making it
