Leonardo, Sewer Samurai + Tatterkite + Viscera Seer + Rakdos, Lord of Riots

Leonardo, Sewer Samurai

Tatterkite

Viscera Seer

Rakdos, Lord of Riots

How it works

1. Cast Tatterkite from your graveyard by paying 0 due to Rakdos. It won't enter with a finality counter on it due to its static ability.
2. Activate Viscera Seer by sacrificing Tatterkite.
3. Repeat.

This loop relies on the brilliant interaction between Leonardo, Sewer Samurai and Tatterkite, transforming your graveyard into a recycling station for artifacts. While Leonardo usually curses creatures cast from the graveyard with a finality counter, Tatterkite's built-in static ability completely blocks that restriction so it enters the battlefield clean every single time. Viscera Seer acts as the necessary outlet to sacrifice Tatterkite, sending it right back to the graveyard where Leonardo can cast it again. Meanwhile, Rakdos, Lord of Riots brings the mana cost down to zero once an opponent has lost life, fueling this endless sacrifice engine for infinite storm count, death triggers, and scrys.
