Remembrance + Mortuary + Altar of Dementia + Crimson Kobolds

Remembrance

Mortuary

Altar of Dementia

Crimson Kobolds

How it works

1. Activate Altar of Dementia by sacrificing Crimson Kobolds.
2. When Crimson Kobolds dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Crimson Kobolds from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Crimson Kobolds and putting it into your hand.
5. Resolve the Altar of Dementia ability.
6. Cast Crimson Kobolds by paying 0.
7. Repeat.

This loop is a masterclass in turning free zero-mana investment into an unstoppable engine, anchored by the tiny frame of Crimson Kobolds. Because they cost nothing to cast, you can repeatedly feed them to Altar of Dementia to mill your opponents out in one fell swoop. The magic happens thanks to Mortuary, which intercepts the dying Kobolds to return them straight to the top of your library, while Remembrance simultaneously lets you tutor a copy right into your hand. By constantly recycling that single card between library, hand, battlefield, and graveyard, you generate an endless storm count and infinite sacrifice triggers without ever running out of resources.
