Sidisi, Regent of the Mire + Sister Hospitaller + Umbral Collar Zealot + Coercive Recruiter

Sidisi, Regent of the Mire

Sister Hospitaller

Umbral Collar Zealot

Coercive Recruiter

How it works

1. Activate Sidisi by tapping it and sacrificing Coercive Recruiter, returning Sister Hospitaller from your graveyard to the battlefield.
2. When Sister Hospitaller enters the battlefield, it triggers, returning Coercive Recruiter from your graveyard to the battlefield and causing you to gain 5 life.
3. When Coercive Recruiter enters the battlefield, it triggers, untapping Sidisi.
4. Activate Umbral Collar Zealot by sacrificing Sister Hospitaller.
5. Repeat.

This clever engine relies on Sidisi, Regent of the Mire acting as a necromancer, leveraging its tap ability to sacrifice Coercive Recruiter and pull Sister Hospitaller out of the graveyard. Once Sister Hospitaller hits the battlefield, its enter-the-battlefield trigger immediately pulls Coercive Recruiter right back out while boosting your life total. Meanwhile, Coercive Recruiter's entry triggers its own ability to untap Sidisi, resetting our main engine piece. Finally, Umbral Collar Zealot provides the necessary outlet to sacrifice Sister Hospitaller and send it back to the graveyard—all while filtering your draws with surveil—leaving Sidisi fresh, untapping, and ready to repeat the entire loop indefinitely.
