This clever loop turns your entire board into a relentless engine of growth and rebirth, anchored by Bartolomé del Presidio as the sacrificial outlet that keeps the gears turning. Whenever you feed a creature to Bartolomé del Presidio, Requiem Angel notices the death and triggers to replace it with a fresh body. Crucially, the replacement effect from Essence of the Wild ensures that the newly created token doesn't arrive as a weak 1/1 Spirit, but instead enters the battlefield as a towering copy of Essence of the Wild itself—which in turn immediately qualifies as another non-Spirit ready to be fed back into Bartolomé del Presidio.
