Leonardo, Sewer Samurai + Solemnity + Bartolomé del Presidio + Kobolds of Kher Keep

Leonardo, Sewer Samurai

Solemnity

Bartolomé del Presidio

Kobolds of Kher Keep

How it works

1. Activate Bartolomé del Presidio 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 loop is a masterclass in bypassing drawbacks, turning a recurring sacrifice into an unstoppable engine. It starts with Bartolomé del Presidio, who gladly consumes your artifacts and creatures to grow stronger, letting you sacrifice Kobolds of Kher Keep over and over again. Thanks to Leonardo, Sewer Samurai, those same Kobolds of Kher Keep can be continuously recast straight from your graveyard during your turn. Usually, Leonardo, Sewer Samurai would saddle them with a finality counter to exile them upon death, but that is where Solemnity comes in—its passive enchantment effect prevents any counters from ever being placed on your creatures, letting the Kobolds of Kher Keep return endlessly without consequence.
