Mortuary + Crimson Kobolds + Bloodflow Connoisseur + Gwenom, Remorseless

Mortuary

Crimson Kobolds

Bloodflow Connoisseur

Gwenom, Remorseless

How it works

1. Activate Bloodflow Connoisseur by sacrificing Crimson Kobolds
2. When Crimson Kobolds dies, Mortuary triggers, putting Crimson Kobolds from your graveyard onto the top of your library.
3. Resolve the Bloodflow Connoisseur ability.
4. Cast Crimson Kobolds from the top of your library by paying 0 life.
5. Repeat.

This ingenious loop leverages Mortuary as a static engine that quietly redirects your fallen creatures straight back to the top of your library instead of letting them rest in the graveyard. With Crimson Kobolds costing zero mana, you can feed it endlessly to Bloodflow Connoisseur to continuously grow your vampire's power while generating an infinite storm count and endless sacrifice triggers. The final piece of the puzzle is Gwenom, Remorseless, whose attack trigger lets you bypass normal casting restrictions to play those recycled Kobolds directly from the top of your library by paying zero life, keeping the engine running indefinitely.
