Mortuary

Impulsive Pilferer

Goblin Bombardment

How it works

3. Resolve the Impulsive Pilferer trigger, creating a Treasure token.
4. Resolve the Mortuary trigger, putting Impulsive Pilferer onto the top of your library from your graveyard.
5. Resolve the Great Goblin trigger, exiling Impulsive Pilferer from the top of your library with the ability to play it until the end of your next turn.
6. Resolve the Goblin Bombardment ability.
7. Activate the Treasure by tapping and sacrificing it, adding .

9. Repeat

This clever loop lets you turn a single creature into a relentless engine of destruction by leveraging a recursive death loop. When you sacrifice Impulsive Pilferer to Goblin Bombardment, Mortuary catches it on its way to the graveyard to neatly place it right back on top of your library. From there, The Great Goblin steps in to exile that very same Impulsive Pilferer off the top upon its death, allowing you to cast it right back out of exile using the mana generated by its own Treasure token.
