Mortuary + Fanatical Firebrand + Susurian Voidborn + Gwenom, Remorseless

Mortuary

Fanatical Firebrand

Susurian Voidborn

Gwenom, Remorseless

How it works

1. Activate Fanatical Firebrand by tapping and sacrificing it.
2. When Fanatical Firebrand dies, Mortuary and Susurian Voidborn trigger.
3. Resolve the Mortuary trigger, putting Fanatical Firebrand from your graveyard onto the top of your library.
4. Resolve the Susurian Voidborn 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 goblin into an inescapable engine by exploiting the top-deck manipulation granted by Gwenom, Remorseless. When you activate Fanatical Firebrand to ping an opponent, its death immediately triggers Susurian Voidborn to drain life while Mortuary quietly places the goblin back on top of your library. From there, Gwenom steps in to let you recast the creature straight off the library, using life instead of mana thanks to its alternative payment clause. Because Fanatical Firebrand costs a mere single mana to begin with, the life payment is completely negligible, allowing you to repeat this cycle indefinitely until your opponents are whittled away to nothing.
