Prowling Geistcatcher + Kiki-Jiki, Mirror Breaker + Goblin Bombardment

Prowling Geistcatcher

Kiki-Jiki, Mirror Breaker

Goblin Bombardment

How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Prowling Geistcatcher with haste.
2. Activate Goblin Bombardment by sacrificing Kiki-Jiki.
3. When Kiki-Jiki dies, the nontoken and token Prowling Geistcatcher's first abilities trigger.
4. Resolve the token Prowling Geistcatcher's trigger, exiling Kiki-Jiki from your graveyard.
5. Resolve the nontoken Prowling Geistcatcher's trigger, doing nothing.
6. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
7. Activate Goblin Bombardment by sacrificing the Prowling Geistcatcher token.
8. When the token Prowling Geistcatcher dies, its second ability and the nontoken Prowling Geistcatcher's first ability triggers.
9. Resolve the nontoken Prowling Geistcatcher trigger, putting a +1/+1 counter on it.
10. Resolve the token Prowling Geistcatcher trigger, returning Kiki-Jiki from exile to the battlefield.
11. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
12. Repeat.

This lethal loop is orchestrated by using Kiki-Jiki, Mirror Breaker to duplicate Prowling Geistcatcher, creating a nested system of exile and return triggers. Whenever you sacrifice a creature to Goblin Bombardment, Prowling Geistcatcher steps in to tuck it away safely, while sacrificing the Geistcatcher token itself allows its leave-the-battlefield trigger to rescue Kiki-Jiki from exile. Because the nontoken Prowling Geistcatcher watches everything unfold without ever truly leaving, each cycle leaves it with an extra +1/+1 counter while feeding Goblin Bombardment an endless stream of ammunition for infinite damage.
