Vizier of Remedies + Heartmender + Phantom Train

Vizier of Remedies

Heartmender

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Heartmender.
2. When Heartmender 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 centers around the unique replacement effect of Vizier of Remedies, which turns the single -1/-1 counter that would normally be placed by persist into zero counters at all. Because Heartmender returns to the battlefield with a completely clean slate, its persist ability can trigger indefinitely every time it is sacrificed. Phantom Train acts as the engine for this loop, letting you feed Heartmender to its sacrifice ability to grow the Train with infinite +1/+1 counters while generating endless entry, death, and sacrifice triggers.
