Remembrance + Mortuary + Crimson Kobolds + Phantom Train

Remembrance

Mortuary

Crimson Kobolds

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Crimson Kobolds.
2. When Crimson Kobolds dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Crimson Kobolds from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Crimson Kobolds and putting it into your hand.
5. Resolve the Phantom Train ability.
6. Cast Crimson Kobolds by paying 0.
7. Repeat.

This ingenious loop turns a zero-mana creature into an endless engine of death and re-entry. By feeding Crimson Kobolds to Phantom Train's sacrifice ability, you trigger a clever tug-of-war between Mortuary and Remembrance: Mortuary instantly rescues the Kobolds from the graveyard and places them back on top of your library, just in time for Remembrance to pluck that exact same copy right out of your library and put it directly into your hand. Because casting Crimson Kobolds costs nothing, you can replay the tiny creature immediately and repeat the entire process, generating an unlimited storm count, sacrifice triggers, and as many +1/+1 counters as you desire for your Phantom Train.
