The deck aims to win by taking away the opponent's creatures and other key cards one by one, and then either slowly killing them with Obzedat's ETB trigger, or a little faster with Blood Barons or Elspeth, or quickly with huge Desecration Demons. It can also win more quickly using Soldiers of the Pantheon as early beatdown, or Lifebane Zombies when sided in.

Their cards are removed either through spot removal or picking them out of their hands with Thoughtseize, Sin Collector or Lifebane Zombie. High Priest of Penance can also help remove things, including enchantments, artifacts and planeswalkers.

Good matchups:

Other midrange decks such as RG Monsters

Bad matchups:

Hard aggro, such as RDW. Should be okay after sideboarding in Blind Obedience, Pharika's Cure, Lifebane Zombie and High Priest.

Hard control, such as UW or Esper. Not sure what to do to improve this matchup. I guess I have to become more of an aggro deck?

Results:None so far with this version, but the deck has done well previously (2nd place Game Day Theros, 6th place GPT Vienna, and 3-1 at FNMs)

The sideboard cards (probably not up-to-date as the deck is undergoing changes):

2x Pithing Needle: Counters Planeswalkers, therling, and stops dangerous things from going monstrous. Will always make the deck vs dangerous 'walkers and vs therling (e.g. UW/Esper Control, RG with Domri).

2x Dark Betrayal: Replaces 2x Doom Blade vs black heavy opponents. Will always make the deck in the mirror match (mostly for Obzedat, but also nice vs big Desecration Demons), and against mono black opponents.

2x Pharika's Cure: Deals with most things in RDW, while also gaining me life to give me longer to stabilize. Usually replaces something that loses me life (Read the Bones/Thoughtseize). Can also replace Devour Flesh if they push out too many creatures to deal with.

2x Blind Obedience: Also vs RDW. Stops their haste guys from hitting me when they should be staying at home, (summoning) sick. Also lets me gain some life (while slowly draining theirs) from my removal spells.

2x Lifebane Zombie: When I need to remove green and/or white threats before they hit the board. Always makes the deck vs Selesnya, picking off stuff like Voice or Trostani. Also very useful against RDW, as it trades with everything they have, is unblockable and can even pick off a Reckoner. Probably also worth it vs RG or GB, getting rid of stuff like Polukranos or Nylea, or maybe a Scavenging Ooze or Reaper. Could be handy in the mirror as well, to get rid of Blood Baron, but I'll probably rely on Thoughtseize for that.

2x Merciless Eviction: They've god gods? Not anymore! Enchantments? Ugh, begone! More planeswalkers than I can needle? Away with thee! Probably replaces some spot removal.

1x Devour Flesh: Moved to sideboard to make room for the third Blood Baron. Goes in vs difficult-to-hit threats like Blood Baron, and probably against Caryatids as well.

1x Sin Collector: Need more of these vs control to take away their Revelations etc.

1x Underworld Connections: For the slow games where I need more cards than Read the Bones can offer, such as control match-ups.
