Hua Tuo, Honored Physician + Verdant Succession + Intruder Alarm + Yahenni, Undying Partisan

Hua Tuo, Honored Physician

Verdant Succession

Intruder Alarm

Yahenni, Undying Partisan

How it works

1. During your precombat main phase, activate Yahenni by sacrificing the additional nontoken green creature.
2. When the creature dies, Verdant Succession triggers.
3. Holding priority, activate Hua Tuo by tapping it, putting the creature from your graveyard onto the top of your library.
4. Resolve the Verdant Succession trigger, searching your library for the sacrificed creature and putting it onto the battlefield.
5. When the creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
6. Resolve the Yahenni ability from step 1.
7. Repeat.
