Heartless Demons

You might want to get some library search to increase your chances of getting heartless summoning, as you currently have roughly 40% chance of having it on your start hand. There are also some demons im wondering as to why you have them:
- Nefarox, you might as well put in a demon with the same, or less, mana cost, like more ob nixilis instead of him, as you don't have a big reason to attack alone.
- Dread cacodemon. He taps all your stuff, and costs 2 more than reiver demon who, for the cost of 2 less in power/toughness, doesn't tap all your stuff (with restrictions) You got enough unconditional destroys already to welcome this 1 loss.
- Abyssal Persecutor, Just as awesome as desecration demon except you can't win with him in play. Seems like a waste of destroy to me, and killing him could give a gap in your "defense" that the opponent can take advantage of and kill you.

So to top it all off, my suggestions (feel free to not follow them if you find my argumentation pointless) are as following:
- Some search for your summoning (demonic/diabolic tutor works well)
- Grab a second rakdos lord of riots. With your endless supply of destroy it'll be easy to get a hit in to play him.
- get rid of nefarox, dread cacodemon and abyssal persecutor. more reiver demons, ob nixilis' and griselbrands
- Maybe get some multicolored lands ( i know they're expensive as hell, but having 3 demons, 2 heartless on your hand and only getting mountains will suck. Hard.
I hope it goes well with the deck, i've had the thought of using heartless for some demons aswell and am considering making a deck with it at some point :)

thanks for the ideas :) ill have to keep testing it out and see what works
