Prowling Geistcatcher + Kiki-Jiki, Mirror Breaker + Blasting Station

Prowling Geistcatcher

Kiki-Jiki, Mirror Breaker

Blasting Station

How it works

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

This loop transforms Kiki-Jiki, Mirror Breaker into an engine of endless rebirth by cloning Prowling Geistcatcher, allowing you to sacrifice both pieces to Blasting Station while safely stashing them away from permanent exile. As the token Geistcatcher hits the graveyard, its leaves-the-battlefield trigger instantly pulls Kiki-Jiki right back to the battlefield to copy the original Geistcatcher all over again. Meanwhile, Blasting Station's untap ability provides the necessary catalyst for every single creature entry and sacrifice, letting you continuously loop the entire setup to deal infinite damage and grow your remaining Geistcatcher infinitely large.
