Remembrance + Mortuary + Bloodflow Connoisseur + Kobolds of Kher Keep

Remembrance

Mortuary

Bloodflow Connoisseur

Kobolds of Kher Keep

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Cast Kobolds of Kher Keep by paying 0.
7. Repeat.

This loop turns a free-to-cast creature into an engine of endless growth and triggers. You begin by using Bloodflow Connoisseur's activated ability to sacrifice Kobolds of Kher Keep, which triggers both Mortuary and Remembrance simultaneously. Mortuary places the fallen Kobolds right back on top of your library, and right behind it, Remembrance lets you tutor another copy straight into your hand. Since the Kobolds cost nothing to cast, you can immediately replay them from your hand for zero mana, feeding the Connoisseur an endless stream of sacrifices to grow infinitely large while piling up infinite death and storm triggers.
