Sharuum the Hegemon + Rescue Skiff + Extruder

Sharuum the Hegemon

Rescue Skiff

Extruder

How it works

1. Cast Rescue Skiff by paying 5.
2. When Rescue Skiff enter the battlefield, it triggers, targeting Sharuum.
3. Holding priority, activate Extruder by sacrificing Rescue Skiff.
4. Resolve the Rescue Skiff trigger, returning Sharuum from your graveyard to the battlefield.
5. When Sharuum enters the battlefield, it triggers, targeting Rescue Skiff.
6. Holding priority, activate Extruder by sacrificing Sharuum.
7. Resolve the Sharuum trigger, returning Rescue Skiff from your graveyard to the battlefield.
8. Repeat from step 2.

This loop sets up a seamless recycling engine between your graveyard and the battlefield, fueled by the sacrifice outlet Extruder. Whenever Rescue Skiff enters the battlefield, its triggered ability targets Sharuum the Hegemon in your graveyard, but sacrificing Rescue Skiff to Extruder in response sends it right back to the graveyard to be retrieved instead. When Sharuum the Hegemon enters the battlefield, its own entry trigger pulls Rescue Skiff back out, only for Sharuum the Hegemon to be immediately sacrificed to Extruder to keep the cycle going. This endless recursion generates infinite sacrifice and death triggers while growing your board with an arbitrary number of +1/+1 counters.
