This deck is mainly built around Smallpox and Bloodchief Ascension.
The only creature card this deck has is Nether Spirit, which means Smallpox is basically just forcing our opponent to sac creatures. Liliana of the Veil and Lightning Bolt should be able to take care of the rest.
Smallpox and Liliana of the Veil also force the opponent to discard. There is additional hand disruption with Blightning and Inquisition of Kozilek.
Bloodchief Ascension can deal a lot of damage over the course of the game with all the cards being discarded. Bloodchief Ascension is actually pretty gross drain with Blightning and Smallpox. Getting the 3 quest counters is really easy because board sweepers and Smallpox don't destroy Chimeric Mass. You can get in for 2 damage every turn with it against control decks that try to clear the board with Supreme Verdict.
Against other decks running more creatures, it still isn't hard to get three counters without doing any combat damage especially if you factor in the sideboard of 4 Collective Brutality and 3 Smash to Smithereens. If your opponent plays a shock land untapped you get a quest counter. If your opponent uses a fetch land on the same turn you used Smallpox, then you get a quest counter. Your opponent is playing a Death's Shadow deck, you get a million quest counters. And so on.
Finally, Smallpox will cause some amount of land destruction. Molten Rain will put an even tighter limit on the amount of available mana the opponent has at any given time. Tectonic Edge and Wildfire never let the opponent ramp too high. This also makes Inquisition of Kozilek even stronger because you can mostly ignore cards CMC 4 or greater due to the amount of land destruction so you don't need to run something like Thoughtseize. Playing Defense Grid in the sideboard also ruins decks trying to play at instant speed. They'll never have enough mana to play any spells on your turn because of the land destruction in this deck.
We are also running 2 Talisman of Indulgence because sometimes you need extra mana or fixing because you destroy or discard your own lands fairly often. It will also give you a Chimeric Mass with more counters which is great because it is one of the main win cons for this deck.
Win conditions are Chimeric Mass, Nether Spirit, and the accumulated burn damage from Molten Rain, Blightning, Smallpox, and Bloodchief Ascension.
