Mortuary + Crimson Kobolds + Yahenni, Undying Partisan + Gwenom, Remorseless

Mortuary

Crimson Kobolds

Yahenni, Undying Partisan

Gwenom, Remorseless

How it works

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

This clever loop turns zero-mana creatures into an endless engine of sacrifice and resurrection. With Gwenom, Remorseless granting you the ability to play cards from the top of your library for free in exchange for life, you can repeatedly deploy Crimson Kobolds at zero mana cost. Yahenni, Undying Partisan provides the necessary outlet to sacrifice the Kobolds, which in turn triggers Mortuary to place them right back on top of your library. As the cycle repeats, Yahenni grows continuously while generating an endless storm of creature deaths and enters-the-battlefield triggers.
