Abzan Ascendancy + Carrion Feeder + Cult Conscript + Pitiless Plunderer

Abzan Ascendancy

Carrion Feeder

Cult Conscript

Pitiless Plunderer

How it works

1. Activate Carrion Feeder by sacrificing Cult Conscript.
2. When Cult Conscript dies, Pitiless Plunderer and Abzan Ascendancy trigger, creating a creature token and a Treasure token.
3. Resolve the Carrion Feeder ability.
4. Activate Carrion Feeder by sacrificing the creature token.
5. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
6. Resolve the Carrion Feeder ability.
7. Activate the Treasures by tapping and sacrificing them, adding 1.
8. Activate Cult Conscript by paying 1, returning it from your graveyard to the battlefield.
9. Repeat.

This elegant recycling loop turns the relentless sacrifice outlet Carrion Feeder into an engine that constantly pumps up its own power and toughness with +1/+1 counters. Pitiless Plunderer and Abzan Ascendancy work in tandem to capitalize on these deaths—the former mints Treasure tokens every time a creature perishes, while the latter replaces your dying nontoken creatures with flying Spirit tokens to keep the fodder flowing. Since a non-Skeleton creature has died under your control, Cult Conscript meets its own revival condition, allowing you to spend the mana generated by the Treasures to bring it right back from the graveyard and repeat the process indefinitely.
