Sharuum the Hegemon + Technomancer + Extruder

Sharuum the Hegemon

Technomancer

Extruder

How it works

1. Cast Sharuum either from your hand or from the command zone by paying 3 plus commander tax if applicable.
2. When Sharuum enters the battlefield, it triggers, targeting Technomancer.
3. Holding priority, activate Extruder by sacrificing Sharuum.
4. Resolve the Sharuum trigger, returning Technomancer from your graveyard to the battlefield.
5. When Technomancer enters the battlefield, it triggers.
6. Holding priority, activate Extruder by sacrificing Technomancer.
7. Resolve the Technomancer trigger, causing you to mill three cards and return Sharuum from your graveyard to the battlefield.
8. Repeat from step 2.

This lovely loop turns an endless cycle of resurrection and sacrifice into a surging wave of power. When Sharuum the Hegemon enters the battlefield, her triggered ability reaches into your graveyard to pull out Technomancer, whose own entry trigger mills cards and brings Sharuum right back into the fold. To keep the gears turning, Extruder acts as the sacrificial engine, using its activated ability to send each legend and construct to the graveyard while growing your creatures with +1/+1 counters. Because Technomancer's total mana value requirement of 6 or less neatly accommodates Sharuum, the two legendary artifact creatures can perpetually trade places in and out of the graveyard.
