Mortuary + Skirk Prospector + Bontu's Monument + Gwenom, Remorseless

Mortuary

Skirk Prospector

Bontu's Monument

Gwenom, Remorseless

How it works

1. Activate Skirk Prospector by sacrificing a Goblin creature with mana value 1 or less.
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Cast the creature from the top of your library by paying 1 life.
4. Bontu's Monument triggers, causing you to gain 1 life and each opponent to lose 1 life.
5. Repeat.

This loop turns a simple sacrifice outlet into a lethal engine by manipulating the top of your library. Whenever you sacrifice a cheap creature to Skirk Prospector for red mana, Mortuary instantly catches it on the way to the graveyard and places it right back on top of your library. That is where Gwenom, Remorseless shines: her attack trigger lets you play cards from the top of your library by paying life instead of mana, allowing you to recast your looped creature for free at the cost of 1 life. Meanwhile, Bontu's Monument actively chips away at your opponents' life totals and offsets the life you pay to Gwenom, Remorseless with a steady stream of lifegain on every cast, letting you safely grind out the game.
