Mortuary + Shilgengar, Sire of Famine + Kobolds of Kher Keep + Gwenom, Remorseless

Mortuary

Shilgengar, Sire of Famine

Kobolds of Kher Keep

Gwenom, Remorseless

How it works

1. Activate Shilgengar by sacrificing Kobolds of Kher Keep
2. When Kobolds of Kher Keep dies, Mortuary triggers, putting Kobolds of Kher Keep from your graveyard onto the top of your library.
3. Resolve the Shilgengar ability.
4. Cast Kobolds of Kher Keep from the top of your library by paying 0 life.
5. Repeat.

This ingenious loop turns the humble, free-to-cast Kobolds of Kher Keep into an infinite engine for sacrifice and death triggers. By feeding the Kobold to Shilgengar, Sire of Famine, you trigger Mortuary to neatly recycle the creature back onto the top of your library. From there, Gwenom, Remorseless steps in with its attack trigger, allowing you to cast that very same Kobold off the top of your library for zero life instead of mana. Repeating this cycle indefinitely leaves you with boundless Blood tokens and endless triggers without ever running out of resources.
