Mortuary + Bloodflow Connoisseur + Bontu's Monument + Gwenom, Remorseless

Mortuary

Bloodflow Connoisseur

Bontu's Monument

Gwenom, Remorseless

How it works

1. Activate Bloodflow Connoisseur by sacrificing a creature with mana value 1 or less.
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Resolve the Bloodflow Connoisseur ability.
4. Cast the creature from the top of your library by paying 1 life.
5. Bontu's Monument triggers, causing you to gain 1 life and each opponent to lose 1 life.
6. Repeat.

This clever engine turns a modest sacrifice outlet into a lethal loop by leveraging alternative casting methods and graveyard recycling. With Bloodflow Connoisseur ready to consume your creatures, Mortuary ensures that any sacrificed creature with a mana value of 1 or less goes straight back to the top of your library instead of staying in the graveyard. From there, Gwenom, Remorseless lets you recast that creature directly off the top of your library by paying life equal to its mana value instead of its mana cost. Meanwhile, Bontu's Monument quietly reduces the casting cost while turning every single loop iteration into an unstoppable drain on your opponents' life totals and a boost to your own.
