Mortuary + Blood Artist + Fanatical Firebrand + Gwenom, Remorseless

Mortuary

Blood Artist

Fanatical Firebrand

Gwenom, Remorseless

How it works

1. Activate Fanatical Firebrand by tapping and sacrificing it.
2. When Fanatical Firebrand dies, Mortuary and Blood Artist trigger.
3. Resolve the Mortuary trigger, putting Fanatical Firebrand from your graveyard onto the top of your library.
4. Resolve the Blood Artist trigger, causing you to gain 1 life and target opponent to lose 1 life.
5. Resolve the Fanatical Firebrand ability.
6. Cast Fanatical Firebrand from the top of your library by paying 1 life.
7. Repeat.

This loop turns a humble Fanatical Firebrand into a relentless engine of destruction by leveraging Gwenom, Remorseless to completely bypass mana costs. Every time the Goblin sacrifices itself, Mortuary ensures it never stays in the graveyard long, instantly sliding it right back to the top of your library. From there, Gwenom, Remorseless lets you recast the creature straight off the library using life instead of mana, while Blood Artist happily drains your opponents dry with every iteration.
