Sister Hospitaller + Wormfang Drake + Phantom Train

Sister Hospitaller

Wormfang Drake

Phantom Train

How it works

1. Cast Wormfang Drake by paying its mana cost.
2. When Wormfang Drake enters, its first ability triggers, exiling Sister Hospitaller.
3. Activate Phantom Train by sacrificing Wormfang Drake.
4. When Wormfang Drake dies, its second ability triggers, returning Sister Hospitaller from exile to the battlefield.
5. When Sister Hospitaller enters, it triggers, returning Wormfang Drake from your graveyard to the battlefield.
6. When Wormfang Drake enters, its first ability triggers, exiling Sister Hospitaller.
7. Resolve the Phantom Train ability.
8. Repeat from step 3.

This clever loop relies on an endless exchange between Wormfang Drake and Sister Hospitaller, where each creature's entry triggers the return or re-entry of the other to perpetually cycle them in and out of play. While this gives you endless entry and death triggers—as well as boundless life from Sister Hospitaller's lifegain—Phantom Train acts as the necessary catalyst to kick off the graveyard recursion by sacrificing the Drake on command. As a bonus, Phantom Train's ability converts that sacrifice into a growing threat by stacking infinite +1/+1 counters onto itself, turning a utility loop into a lethal powerhouse.
