The deck does a few things. Firstly, if you get Waste Not, all of your discard becomes pure value. Dark Deal and Burning Inquiry hit especially hard, either giving you a board full of zombies or ramping into an Empty the Pits to give you a board full of zombies. The discard also acts as disruption when Waste Not isn't around, making it easier to advance the Empty the Pits plan.

Burning Inquiry, Dark Deal, Faithless Looting, and Cathartic Reunion all cycle through your deck to find what you need, as well as fill the graveyard in preparation for Empty the Pits. Evolving Wilds is a budget alternative to fetchlands. Fills the graveyard, fixes mana, but comes into play tapped. Not sure how many of that effect I want right now.

Lightning Bolt is one of the best red spells ever, no need to go into that. Fiery Temper can imitate it sometimes without even costing you a card, though not having played it yet I'm not sure whether it's too situational. Seems cool, and I'm a sucker for the timeshifted rarity.

The landbase for the most part isn't terribly scientific, started with what I have lying around and added enough cheap duals to get what felt like sufficient mana fixing.

The list is really rough, so it could use feedback. All suggestions are appreciated, but this is a budget deck at heart, so I'm probably not running Liliana of the Veil anytime soon. I realize Thoughtseize isn't budget, I just happen to own them already. Blackmail and Duress are solid substitutions, as would anything else that fits the deck's general game plan.
