This deck has good synergy, good removal, and good pressure; not to mention it's fun to play :)
Deck Run-Down
Daring Skyjek- a potential zombie that provides good early pressure and a semi-flyer.
Desecration Demon- an absolute powerhouse in the meta game right now so why not have one?
Detention Sphere- good against any creature deck, especially pack rat.
Doom Blade- your standard removal, more in the board if need be.
Far//Away- nice card that breaks tempo and provides variety to the deck.
Imposing Sovereign- a potential zombie with a pretty relevant effect against any creature deck.
Lyev Skyknight- 3/1 flyer with detain and a potential zombie.
Soldier of the Pantheon- really great one-drop and potential zombie.
Supreme Verdict- odd card but you basically hold it to get out of a sticky situation and Xathrid Necromancer makes this card a whole lot better while adding synergy.
Ultimate Price- another standard removal, but quick to remove against multicolored decks.
Whip of Erebos- a real game changer and I think it fits well in this deck.
Xathrid Necromancer- the card that kind of brings the whole decks synergy together.
Cartel Aristocrat- good card to dodge removal and pairs well with the necromancer.
Frontline Medic- great against sphix's-revelation and it combos well with Supreme Verdict after combat and the battalion allows you to just bash relentlessly.
Obzedat, Ghost Council- great card that tucks games away and can pull you out of a sticky situation.
Sideboard
Blood Baron of Vizkopa- obvious sideboard card with it being pro R/W and all.
Doom Blade- comes in against any non-black decks.
Far//Away- good if you need more removal or against hexproof.
Ultimate Price- great against the mono devotion decks and mono colored decks in general.
Negate- obvious side in for when your opponent isn't playing a lot of creatures.
Pay No Heed- a very situational card, but when it's needed it's good.
Thoughtseize- really good against any deck.
Underworld Connections- comes in if I need to get ahead of my oponent.
