Remembrance + Mortuary + Altar of Dementia + Crookshank Kobolds

Remembrance

Mortuary

Altar of Dementia

Crookshank Kobolds

How it works

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

This clever loop relies on the zero-mana cost of Crookshank Kobolds to keep the engine spinning indefinitely. Whenever you sacrifice the Kobolds to Altar of Dementia, Mortuary steps in to instantly recycle the card from your graveyard straight to the top of your library. At the same exact time, Remembrance exploits the creature's death by fetching another copy right into your hand, ensuring you have the ammo to recast it for free. By continually looping these triggers, you can mill out any opponent's entire library while generating an endless stream of sacrifice and death triggers.
