Mortuary + Goblin Bombardment + Phyrexian Walker + Gwenom, Remorseless

Mortuary

Goblin Bombardment

Phyrexian Walker

Gwenom, Remorseless

How it works

1. Activate Goblin Bombardment 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 Goblin Bombardment ability.
4. Cast Phyrexian Walker from the top of your library by paying 0 life.
5. Repeat.

This engine relies on recycling a single artifact creature through an infinite sacrifice loop, turning zero-cost cardboard into boundless devastation. You feed zero-mana creatures like Phyrexian Walker to Goblin Bombardment to deal endless damage, using Mortuary to instantly intercept them upon death and tuck them back onto the top of your library. From there, Gwenom, Remorseless provides the crucial top-deck permission and life-payment alternative to recast the Walker for free on command, bypassing mana costs entirely.
