Sharuum the Hegemon + Technomancer + Krark-Clan Ironworks

Sharuum the Hegemon

Technomancer

Krark-Clan Ironworks

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 Krark-Clan Ironworks 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 Krark-Clan Ironworks 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 recursive loop relies on Sharuum the Hegemon and Technomancer endlessly looping between the battlefield and the graveyard, with Krark-Clan Ironworks acting as the engine that both clears the board and fuels the entire operation with colorless mana. When Sharuum enters the battlefield, its triggered ability targets Technomancer in your graveyard, but sacrificing Sharuum to Krark-Clan Ironworks in response ensures it hits the graveyard just in time. When Technomancer then enters the battlefield, its own entry trigger mills three cards and brings Sharuum right back, allowing you to sacrifice Technomancer to Krark-Clan Ironworks as well to repeat the cycle indefinitely.
