Main idea: Use Waste Not to gain zombie tokens and land through discard spells. Eventually, use Empty the Pits with Nykthos, Shrine to Nyx to get some more creatures to swing with. Granted, devotion won't be super high, but Rakshasa's Secret gives me a bit of a graveyard to delve with.

Master of the Feast and Fate Unraveler, paired with Sign with Blood seem like a decent way to get some life down, as well as fill their hand for more discard, and in turn, more tokens.

Concerns: Not enough low mana creatures and removal, but not sure what to add/take out.
