Underworld Cerberus Is a great 5 drop, i would main board it and only put in Sire Of Insanity when playing against an esper or another form of control. Anger of the Gods is another card that should be in here for sure as well as Thoughtseize or Duress / +2 Hero's Downfall for sure and -1 Doomblade

As for sideboard +1 Slaughter Games and +3 Dark Betrayal

I love all of these suggestions Nekrocity.The only one I'm not sure about is Thoughtseize or Duress being mainboard. Both would be good to see someone's hand but I feel like those spots would be better filled with control spells. What is your take on this idea? what would you take out for them?I'm going to try to rework some of your other ideas in now. Thanks so much for the feedback!

Guttersnipe + Anger of the Gods seems kind of a bad combo. But I guess it's against those aggro decks where you actually wouldn't play a G-snipe before anyway, right?

Also I'd totally exchange the SB Elixir vs two more Needles, or are you facing a lot of mill decks?

Well with all the kill spells and Rakdos's Return using them while Guttersnipe is on the field is perfect. yeah i think with agro i would hold of on playing gutter until after the anger goes off

No I love that idea =] i almost never actually side in the Elixirs

nice deck it looks like it hurts hard! love it

Nice deck! Played it a few times against my fog deck and every game looked like it was in my favor until Master of Cruelties hit. Nasty stuff.

This deck could use a couple Rakdos Keyrune s. Its the best keyrune by far and helps your high curve.

You need to add Rakdos, Lord of Riots great card for your deck
