How it works
Activate Kiki-Jiki by tapping it, creating a token copy of Lumbering Battlement.
When the Lumbering Battlement token enters the battlefield, it triggers, exiling Kiki-Jiki until Lumbering Battlement leaves the battlefield.
Activate Bloodflow Connoisseur by sacrificing the Lumbering Battlement token.
When the Lumbering Battlement token dies, Kiki-Jiki is returned from exile to the battlefield.
Resolve the Bloodflow Connoisseur ability.
Repeat.
This clever loop relies on Kiki-Jiki, Mirror Breaker creating temporary copies of Lumbering Battlement, whose entry trigger exiles the goblin to safely bypass its usual end-step sacrifice. Each time a token copy enters, its ability consumes Kiki-Jiki until Bloodflow Connoisseur steps in to sacrifice the token, immediately releasing the imprisoned goblin back to the battlefield. Because Kiki-Jiki’s haste allows it to restart the process fresh every iteration, Bloodflow Connoisseur grows endlessly large while farming an infinite stream of sacrifice and exit-the-battlefield triggers.
