Leonardo, Sewer Samurai + Solemnity + Memnite + Phantom Train

Leonardo, Sewer Samurai

Solemnity

Memnite

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Memnite.
2. Cast Memnite from your graveyard by paying 0. It will not enter with a finality counter on it due to Solemnity.
3. Repeat.

This clever loop turns the graveyard into an endless engine by pairing Leonardo, Sewer Samurai with Solemnity to completely bypass the finality counters that would normally exile your cast creatures. You simply sacrifice Memnite to fuel Phantom Train's ability—which simultaneously pumps the Train with a +1/+1 counter and clears the path—allowing you to recast the zero-mana artifact creature right back out of your graveyard. Thanks to Solemnity's static ability, even the finality counters imposed by Leonardo are blocked entirely, letting you repeat this sacrifice-and-cast cycle infinitely for boundless triggers and a massive Phantom Train.
