Mortuary + Moldervine Reclamation + Fanatical Firebrand + Gwenom, Remorseless

Mortuary

Moldervine Reclamation

Fanatical Firebrand

Gwenom, Remorseless

How it works

1. Activate Fanatical Firebrand by sacrificing it.
2. When Fanatical Firebrand dies, Mortuary and Moldervine Reclamation trigger.
3. Resolve the Mortuary trigger, putting Fanatical Firebrand from your graveyard onto the top of your library.
4. Resolve the Moldervine Reclamation trigger, causing you to gain 1 life and draw a card.
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 a lethal recurring engine by exploiting Gwenom, Remorseless to completely bypass mana costs from the top of your library. Whenever Fanatical Firebrand sacrifices itself to ping a target, Mortuary immediately intercepts it on the way to the graveyard to stack it right back on top of your library, while Moldervine Reclamation cushions your life total and draws you a card to keep the momentum going. Because Gwenom allows you to cast that freshly stacked goblin for a mere 1 life instead of its mana cost, you can recast it instantly and repeat the cycle to generate a relentless storm of damage and triggers.
