Zombie Infestation + Queen Allenal of Ruadach + Yahenni, Undying Partisan + Tresserhorn's Lord, Returned

Zombie Infestation

Queen Allenal of Ruadach

Yahenni, Undying Partisan

Tresserhorn's Lord, Returned

How it works

1. Activate Zombie Infestation by discarding two cards, creating a 2/2 Zombie creature token and a 1/1 Soldier creature token.
2. Activate Yahenni twice by sacrificing the Zombie and Soldier.
3. When the Zombie and Soldier die, Tresserhorn's Lord triggers twice, causing you to draw two cards.
4. Resolve both Yahenni abilities.
5. Repeat.

This engine starts by pumping your hand into the graveyard using Zombie Infestation to spin up a 2/2 Zombie and, thanks to the replacement effect of Queen Allenal of Ruadach, an extra 1/1 Soldier token into the bargain. You then feed those fresh bodies directly to Yahenni, Undying Partisan, whose sacrifice outlet not only keeps the board clear but also pumps its stats. Every time you sacrifice a creature to fuel Yahenni, Tresserhorn's Lord, Returned capitalizes on the death trigger to replace the discarded cards by drawing you fresh ones, turning your discarded resources into a continuous cycle of card draw and creature tokens.
