Sharuum the Hegemon + Technomancer + Bloodflow Connoisseur

Sharuum the Hegemon

Technomancer

Bloodflow Connoisseur

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 Bloodflow Connoisseur 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 Bloodflow Connoisseur 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 clever loop relies on trading legends back and forth from the graveyard using their entry triggers to sustain each other indefinitely. When you cast Sharuum the Hegemon, its entrance targets Technomancer in your graveyard, but before that trigger resolves, Bloodflow Connoisseur sacrifices Sharuum to put a +1/+1 counter on itself. Sharuum's trigger then resolves to bring back Technomancer, whose own entrance trigger mills three cards and immediately reanimates Sharuum from the graveyard—allowing Bloodflow Connoisseur to sacrifice Technomancer in response and close the loop.
