Urza, Lord High Artificer + Deadeye Navigator + Krark-Clan Ironworks

Urza, Lord High Artificer

Deadeye Navigator

Krark-Clan Ironworks

How it works

1. Activate Urza by paying 1, blinking it.
2. When Urza enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
3. Resolve the Deadeye Navigator trigger, repairing it and Urza.
4. Resolve the Urza trigger, creating a 0/0 Construct artifact creature token.
5. Activate Urza's first ability by tapping the Construct, adding .
6. Activate Krark-Clan Ironworks by sacrificing the Construct, adding CC.
7. Repeat.

This loop begins by using Urza, Lord High Artificer to tap the Construct artifact token it creates for blue mana, which feeds the blink ability granted by Deadeye Navigator via soulbond. Krark-Clan Ironworks then steps in to turn those same tokens—or any other artifacts you generate—into explosive colorless mana to sustain the loop and fund Urza's massive ability. By repeatedly cycling Urza through exile and back to the battlefield, you generate infinite entry and death triggers while eventually digging through and casting every spell in your entire library.
