This loop turns a humble lifegain trigger into an engine of endless growth and sacrifice. By using Bartolomé del Presidio to repeatedly sacrifice Kitchen Finks, you exploit persist to bring the Finks back, though it would normally return neutralized with a -1/-1 counter. However, Cleric Class steps in to completely break the math: its passive replacement effect boosts your baseline lifegain while its Level 2 ability places a +1/+1 counter on Kitchen Finks every time you gain life. Because +1/+1 and -1/-1 counters immediately annihilate each other through state-based actions, that counter completely wipes away the persist counter, allowing Kitchen Finks to return fresh and ready to be sacrificed all over again.
