you may want to use this:
Volcano Hellion with your Stuffy Doll in play and your opponent with less life than you should be an instant win

i have this 2 decks that focus on killing the opponent by using the same idea but no the same cards thou

Hellion Reckoner

Circle of infinite Damage

Nin, the Pain Artist works VERY well with Stuffy Doll

Gratuitous Violence is similar to Curse of Bloodletting , but allows you to do damage to more opponents

Krenko's Command seems kinda silly in here. i assume they're there to block? other things to consider might be Sigil of Sleep , Quicksilver Dagger (to put on Fog Bank ), or even just a few Counterspell s

i really like the synergy you're going for with Fatal Attraction and Stuffy Doll , +1 from me

Both Volcano Hellion and Nin, the Pain Artist are awesome suggestions, thank you!

Ruric: both of those decks seem pretty cool, +1s

greyninja: Gratuitous Violence would be good, but the group i play with basically plays modern now, but i put casual because it's not too competitive. The 'rule' is 'modern' frames with no white edges. But thank you still!

And yeah the Krenko's Command s are just in case i need blockers or more creatures for Blasphemous Act

Spirit Link or Lifelink might be worth a white splash

That's what Basilisk Collar was for, and it worked better than splashing white because i could also tutor it with a Fabricate :P

But i need to update this deck anyways

A Riot Control would suck if you got that off

So would Path to Exile

Also, might I suggest streamlining it a bit?
