Mortuary + Viscera Seer + Phyrexian Walker + Gwenom, Remorseless

Mortuary

Viscera Seer

Phyrexian Walker

Gwenom, Remorseless

How it works

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

This clever loop uses Mortuary as the engine to immediately recycle any creature sent to the graveyard back to the top of your library. By sacrificing the zero-cost Phyrexian Walker to Viscera Seer, you trigger Mortuary to place the Walker right back where you need it, letting Viscera Seer fuel infinite scry 1s and death triggers. While Gwenom, Remorseless isn't strictly necessary for the core loop, its ability to cast spells from the top of your library (paying life instead of mana) highlights how easily such top-deck manipulation can be leveraged when you need to cast your recycled threats.
