My favorite thing to do in Magic is cheat mana costs for big scary permanents. This deck excels in that, using cheap pinger effects like
Spear Spewer
to enable Rakdos to be played, and then accelerating out damage to our opponents to cheat on the mana costs of big scary demons.
I don't play the Eldrazi Titans in this deck because I'm already playing them in my Kozilek, the Great Distortion deck, and I like the variety of having a light Demon typal theme.
