Precursor Golem + Rite of Replication + Jace, Wielder of Mysteries + Cloak of Feathers

Precursor Golem

Rite of Replication

Jace, Wielder of Mysteries

Cloak of Feathers

How it works

1. Cast Rite of Replication with kicker by paying 7, targeting Precursor Golem.
2. Precursor Golem's second ability triggers, creating a kicked copy of Rite of Replication targeting every other Golem.
3. Resolve the first Rite of Replication, creating five token copies of the Golem it is targeting.
4. If the Golem was Percursor Golem, the Percursor Golem tokens enter the battlefield, triggering their first abilities, creating a total of ten 3/3 Golem artifact creature tokens.
5. Repeat from step 3 for each other Rite of Replication.
6. Cast Cloak of Feathers by paying , targeting any Golem.
7. The six Percursor Golems' second abilities each trigger, creating six copies of Cloak of Feathers targeting every other Golem.
8. Resolve the first Cloak of Feathers, causing you to draw a card.
9. Repeat step 8 until you draw from an empty library, causing you to win the game.

This spell-copying loop hinges entirely on Precursor Golem’s unique ability to multiply single-target instant and sorceries across every eligible Golem on the battlefield. When you cast a kicked Rite of Replication targeting the original Precursor Golem, the Golem's trigger turns that single spell into a massive wave of copies targeting every other Golem present, filling the board with an overwhelming army of Golem artifact tokens. Once your opponents are buried under this mechanical horde, you shift gears by casting Cloak of Feathers targeting one of your many Golems. Precursor Golem's multiplication effect triggers again to copy the cantrip across your entire army, allowing you to cycle through your deck until your library is completely empty. Finally, the passive replacement effect of Jace, Wielder of Mysteries steps in to intercept your next draw from an empty library, transforming your self-milling victory into an instant win.
