Mortuary + Vein Ripper + Fanatical Firebrand + Gwenom, Remorseless

Mortuary

Vein Ripper

Fanatical Firebrand

Gwenom, Remorseless

How it works

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

This clever loop turns a tiny goblin into a fatal engine of attrition by manipulating the top of your library. When you activate Fanatical Firebrand, its sacrifice triggers Mortuary to place it right back onto your library rather than staying in the graveyard. Meanwhile, Vein Ripper watches every creature die to drain your opponent's life total while padding your own life pad. This lifegain is crucial because Gwenom, Remorseless lets you bypass mana costs to recast the Firebrand straight from the top of your library by paying life instead, sustaining an endless cycle of sacrifice, damage, and rebirth.
