Mortuary + Memnite + Bloodflow Connoisseur + Gwenom, Remorseless

Mortuary

Memnite

Bloodflow Connoisseur

Gwenom, Remorseless

How it works

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

This clever loop sets up an infinite engine using Gwenom, Remorseless to peer into the future and bypass mana costs entirely. With Gwenom's attack trigger active, you can continuously cast Memnite from the top of your library for zero life, feeding it directly into Bloodflow Connoisseur's sacrifice ability to grow the vampire larger with endless +1/+1 counters. Every time Memnite hits the graveyard, Mortuary quietly ensures the artifact creature immediately returns to the top of your library to restart the cycle.
