Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Melira's Keepers + Phantom Train

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Melira's Keepers

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Melira's Keepers
2. When Melira's Keepers dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to its static effect.
3. Resolve the Phantom Train ability.
4. Repeat.

This clever loop revolves around Phantom Train's ability to sacrifice a creature to grow larger, which we feed with Melira's Keepers. Because Melira's Keepers features a static ability preventing counters from being placed on it, the persist granted to it by Isilu, Carrier of Twilight (the back face of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight) triggers without the crippling drawback of a -1/-1 counter when it dies. This allows Melira's Keepers to continuously return to the battlefield endlessly ready to be sacrificed again, letting Phantom Train accumulate infinite +1/+1 counters while generating an unlimited stream of sacrifice and death triggers.
