rakdos idea...possibly

For starters you're only at 59 cards... so there's that.

If you're going the aggro route, I would suggest looking at the GP Santiago deck and use it as a starting point.  I know net-decking is "lame" but that deck REALLY shines.  Among the cards you might want to look into is Xathrid Necromancer as it can offer some really solid resilence for your side of the board.

I'd probably pull Rakdos himself as, unfortunately, the likelihood you get him out isn't all that great.  The added damage condition to his casting is a bit of a pain and makes him inconsistent.

Another card I really think is under-appreciated is Stab Wound.  It's a bit on the pricey side, but think about the havoc you wreck on Nightveil Specter and things of that nature... that and the 2 damage per turn really does add up.  If you're totally wanting to jank it up... Havoc Festival (the wtf looks you'll get will be hilarious).

Back to reality though, you're definitely going to want to add the Necromancer, Tormented Hero and potentially you could toss in Akroan Crusader and/or Foundry Street Denizen to improve the speed of the deck. 

I'd also yank Lily as this version of her just really isn't all that good.

Oh yeah... Dreadbore is going to be a lot better than your other removal.  I also can't see much sense behind Rakdos Charm in the mainboard...

I hope some of this helps...
