Patron of the Moon + Uyo, Silent Prophet + Culling the Weak

Patron of the Moon

Uyo, Silent Prophet

Culling the Weak

How it works

1. Cast Culling the Weak by paying and sacrificing a creature.
2. Holding priority, activate Uyo by paying 2 and returning two lands to your hand from the battlefield, copying Culling the Weak.
3. Resolve the copy of Culling the Weak, adding .
4. Activate Patron of the Moon by paying 1, putting two lands onto the battlefield tapped from your hand.
5. Repeat from step 2.
6. Once you have infinite mana, you may target any other instant and/or sorcery spell on the stack to get infinite copies of them.

This elegant loop turns Uyo, Silent Prophet into a master copyist by leaning on the mana-generating engine of Culling the Weak, which is fed by sacrificing a creature. To sustain Uyo's activation cost of returning two lands to your hand, Patron of the Moon steps in with its ability to instantly drop those same lands right back onto the battlefield. By continuously cycling lands between your hand and the battlefield with Patron of the Moon while feeding the loop with Culling the Weak, you generate infinite black mana and infinite spell copies, creating a dazzling display of arcane repetition.
