This loop puts the magical ingenuity of Urza, Lord High Artificer into overdrive by repeatedly flickering him with Deadeye Navigator's soulbond ability. Whenever Urza re-enters the battlefield, Mondrak, Glory Dominus steps in to double the resulting robot army, turning a single Construct into a pair of artifacts ready to be tapped for blue mana via Urza's built-in mana ability. Because those very same tokens generate the exact mana needed to keep paying for Deadeye Navigator's blink effect, the engine sustains itself indefinitely while flooding your board with an endless sea of artifact creatures.
