Urza, Lord High Artificer + Deadeye Navigator + Precursor Golem

Urza, Lord High Artificer

Deadeye Navigator

Precursor Golem

How it works

1. Activate Precursor Golem by paying 1, blinking it.
2. When Precursor Golem enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
3. Resolve the Deadeye Navigator trigger, repairing it and Precursor Golem
4. Resolve the Precursor Golem trigger, creating two artifact tokens.
5. Activate Urza's first ability twice by tapping Precursor Golem and another artifact, adding .
6. Repeat.

This clever loop centers around Deadeye Navigator pairing up with Precursor Golem to enable endless blinking, which repeatedly triggers the Golem's entrance to flood the board with an army of Golem artifact creature tokens. Urza, Lord High Artificer acts as the engine's powerhouse by turning those newly generated artifacts—and the Golems themselves—into mana sources, tapping them for blue mana to endlessly pay for Deadeye Navigator's blink ability while leaving plenty of extra blue mana to spare. With an infinite supply of blue mana and artifacts entering and leaving the battlefield at your whim, Urza's massive mana-sink ability can then be activated repeatedly to exile your entire library and cast every single spell within it for free, sealing the game's victory.
