Mortuary + Goblin Bombardment + Kobolds of Kher Keep + Gwenom, Remorseless

Mortuary

Goblin Bombardment

Kobolds of Kher Keep

Gwenom, Remorseless

How it works

1. Activate Goblin Bombardment by sacrificing Kobolds of Kher Keep
2. When Kobolds of Kher Keep dies, Mortuary triggers, putting Kobolds of Kher Keep from your graveyard onto the top of your library.
3. Resolve the Goblin Bombardment ability.
4. Cast Kobolds of Kher Keep from the top of your library by paying 0 life.
5. Repeat.

By pairing Goblin Bombardment with Mortuary, you create a closed loop where any sacrificed creature immediately recycles back to the top of your library instead of staying in the graveyard. This is where Gwenom, Remorseless earns its keep, granting you the crucial ability to look at and cast creatures directly from the top of your library while bypassing their mana costs by paying life instead. Since Kobolds of Kher Keep costs zero mana, you can cast it repeatedly for free using Gwenom's life-payment effect every time Mortuary places it back on top, fueling an infinite loop of sacrifices and damage to close out the game.
