3. Holding priority, activate Ashnod's Altar 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 Ashnod's Altar by sacrificing Technomancer.
7. Resolve the Technomancer trigger, causing you to mill three cards and return Sharuum from your graveyard to the battlefield.
