Leonardo, Sewer Samurai + Solemnity + Kobolds of Kher Keep + Phantom Train

Leonardo, Sewer Samurai

Solemnity

Kobolds of Kher Keep

Phantom Train

How it works

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

This clever graveyard loop puts Solemnity's prevention ability to brilliant use, turning a harsh drawback into a limitless engine. While Leonardo, Sewer Samurai normally brands anything rescued from your graveyard with a finality counter—exiling it the moment it dies—Solemnity steps in to ensure no counters can ever be placed on your creatures. This allows you to endlessly sacrifice Kobolds of Kher Keep to fuel Phantom Train, growing the Vehicle's stats while immediately casting the zero-mana Kobolds right back out of the graveyard to repeat the cycle infinitely.
