When Wormfang Drake enters, its first ability triggers, exiling Sister Hospitaller.
Activate Viscera Seer by sacrificing Wormfang Drake.
When Wormfang Drake dies, its second ability triggers, returning Sister Hospitaller from exile to the battlefield.
When Sister Hospitaller enters, it triggers, returning Wormfang Drake from your graveyard to the battlefield.
When Wormfang Drake enters, its first ability triggers, exiling Sister Hospitaller.
Resolve the Viscera Seer ability.
Repeat from step 3.
This elegant loop creates a perpetual motion machine between the graveyard and the battlefield by leveraging Wormfang Drake's enter and leave triggers to infinitely recycle Sister Hospitaller. Each time the Drake returns the Hospitaller, her *Medicus Ministorum* ability brings the Drake straight back from the grave while padding your life total, neatly satisfying the Drake's exile requirement. Meanwhile, Viscera Seer acts as the necessary catalyst and safety valve, letting you sacrifice the Drake on demand to kickstart the loop while turning every iteration into infinite scries to sculpt your library.
