Urza, Lord High Artificer + Deadeye Navigator + Phyrexian Altar

Urza, Lord High Artificer

Deadeye Navigator

Phyrexian Altar

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 Phyrexian Altar by sacrificing the Construct, adding 1.
7. Repeat.

This ingenious loop harnesses Urza, Lord High Artificer both as a mana engine and as the source of our sacrificial fodder, turning its own entry trigger into an endless parade of Construct tokens. By leveraging Deadeye Navigator's soulbond ability to repeatedly blink Urza, we continually refresh our token supply without ever running out of fuel. Phyrexian Altar acts as the necessary outlet to instantly convert those freshly minted Constructs into colored mana, while Urza’s built-in mana ability taps them for blue mana along the way to pay for the blink.
