Vizier of Remedies + Thunderblust + Phantom Train

Vizier of Remedies

Thunderblust

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Thunderblust.
2. When Thunderblust dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Vizier of Remedies.
3. Resolve the Phantom Train ability
4. Repeat.

This clever loop hinges on exploiting the counter-mitigation of Vizier of Remedies, which steps in whenever Thunderblust's persist ability tries to place a -1/-1 counter upon its return, reducing the counter count to zero and allowing persist to trigger indefinitely. To keep the engine running, Phantom Train serves as the necessary sacrifice outlet, turning the recurring death of Thunderblust into an endless stream of sacrifice triggers while simultaneously stacking infinite +1/+1 counters onto itself.
