The Aristocrats (Modern)

Traditional aristocrats deck without anything crazy.

The main sacrifices that can be sacrificed and come back multiple times per turn are:
Gravecrawler, very cheap, but requires us to have another zombie in play. Dread Wanderer can come back from the graveyard to allow this;
Reassembling Skeleton, more expensive than Gravecrawler, but doesn't have any conditions;

Other sacrifices are:
Gutterbones, cheap cast, but expensive return cost (comes back to the hand and not the battlefield);
Clattering Augur, expensive, but serves as a draw outlet;
Dread Wanderer, expensive, but enables Gravecrawler;

Our sacrificers are:
Cartel Aristocrat, gets protection and can attack unblocked;
Viscera Seer, scry;
Carrion Feeder, gets bigger and allows us to bring Gravecrawler back;

Sacrifice payoffs are:
Cruel Celebrant, drains for 1 each time one of our creatures dies;
Blood Artist, also drains for 1, but works for opponents creatures too;
Athreos, God of Passage, gives the opponent the option to take a hard hit every time we sacrifice a creature or allow us to bring the sacrificed creatures to our hand, making it cheaper to recast them and allows us to sac and bring back creatures that normally won't come back.

Other cards:
Damn is a good board wipe that can be followed by casting creatures back from the graveyard. Can also serve as an early game targeted removal.
