Mortuary + Pitiless Plunderer + Bloodflow Connoisseur + Benjamin Sisko, Besieged

Mortuary

Pitiless Plunderer

Bloodflow Connoisseur

Benjamin Sisko, Besieged

How it works

1. Activate Bloodflow Connoisseur by sacrificing the nontoken creature.
2. When the creature dies, Mortuary and Pitiless Plunderer trigger.
3. Resolve the Mortuary trigger, putting the creature from your graveyard onto the top of your library.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Resolve the Bloodflow Connoisseur ability.
6. Activate the Treasure by tapping and sacrificing it, adding one mana of any color.
7. Cast the creature from the top of your library by paying its mana cost
8. Repeat.

This clever loop relies on Benjamin Sisko, Besieged to turn the top of your library into an extension of your hand, allowing you to continually recast your sacrificed creatures. Every time you use Bloodflow Connoisseur to sacrifice a creature, Pitiless Plunderer funds the spellcasting by generating a Treasure token, while Mortuary neatly recycles the dead creature back to the very top of your library. As the cycle repeats, Bloodflow Connoisseur grows infinitely larger with endless +1/+1 counters while triggering an avalanche of deaths and artifact events.
