Combo: Get Saffi and Loyal Retainers in play to create a semi-infinite loop of creatures dieing. Use those effects to do one of three things:

Entomb Bridge from Below before you start the cycle to create a Zombie Clown Car

After the loop, cast Caller of the Claw to create an arbitrarily large number of bears, then drop Concordant Crossroads for the win.

After the loop, cast Bitter Ordeal targeting your opponent. Have a Bojuka Bog or something else ready to play afterwards.

Have Blood Artist in play and start the loop. You win.

Uses Necroplasm as a board sweeper. With a sac outlet you can blow out token decks.
