Remembrance + Mortuary + Altar of Dementia + Kobolds of Kher Keep

Remembrance

Mortuary

Altar of Dementia

Kobolds of Kher Keep

How it works

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

This delightful zero-mana loop turns the humble Kobolds of Kher Keep into an unstoppable engine of endless sacrifice. Because the tiny kobold costs nothing to cast, you can repeatedly feed it to Altar of Dementia to mill an opponent out while generating an infinite storm count and a storm of death triggers. Whenever it heads to the graveyard, Mortuary neatly recycles it right back to the top of your library. That timely placement is instantly exploited by Remembrance, which snatches another copy straight out of your library and puts it right back into your hand, ready to be cast for free all over again.
