I mostly play casual games with friends, often 1v1.

I really enjoy the mechanics of this deck, although it seems to be a bit too slow and unreliable against most opponents. The major drawbacks I see are the lack of removal and poor defenses against flying creatures and control decks.

Any suggestion to improve the deck while keeping the "non-token sacrifice" mechanic intact is quite welcome!

This deck focuses on maintaining a stream of creeatures to sacrifice, and takes advantage of that sacrifice for various purposes (card/board advantage, face damage).

Act of Treason or Harness by Force + Sacrifice helps us deal with most big creatures, while Collateral Damage takes care of smaller opponents.

Reassembling Skeleton and Tenacious Dead can be sacrificed multiple times per turn for 1B.

Sultai Emissary and Qarsi High Priest summon new bodies to sacrifice, or sometimes creatures like Jeering Instigator (which can then be turned for only 1R) or Ruthless Ripper (for 2 "free" damage).

Nantuko Husk is the main sacrifice trigger, along with Tymaret, the Murder King which can also be triggered from the graveyard.

Outpost Siege helps us go through the deck quicker with its first ability, making sure we have all the engine pieces out as fast as possible. It synergizes well with the sacrifice mechanic with its second ability.

Once two or more Grim Haruspex are on the battlefield, it's easy to draw multiple 1-drops with a single sacrifice, adding more fuel to the fire for a cheap cost.
