Ob Nixilis, Captive Kingpin

Mortuary

Goblin Arsonist

Skirk Prospector

How it works

1. Activate Skirk Prospector by sacrificing Goblin Arsonist, adding .
2. When Goblin Arsonist dies, it and Mortuary trigger.
3. Resolve the Mortuary trigger, putting Goblin Arsonist on top of your library from your graveyard.
4. Resolve the Goblin Arsonist trigger, dealing 1 damage to an opponent.
5. Ob Nixilis triggers, putting a +1/+1 counter on itself, and exiling Goblin Arsonist from the top of your library with the ability to play it until your end step.
6. Cast Goblin Arsonist from exile by paying .
7. Repeat.

This loop transforms a humble Goblin Arsonist into an endless engine of destruction, fueled by Skirk Prospector turning the Goblin into the red mana needed to recast it from exile. While Mortuary ensures the Arsonist never stays dead by seamlessly sliding it back to the top of your library every time it hits the graveyard, Ob Nixilis, Captive Kingpin turns every single point of ping damage into a +1/+1 counter and card advantage, letting you immediately play the Arsonist right back out. Together, these pieces feed off one another to continuously sacrifice, burn, and recast until your opponents are overwhelmed by infinite damage and counters.
