The 4 combo pieces

How to execute it

  1. Activate Arcbound Worker by paying {1}{U}, blinking it.
  2. Arcbound Worker leaves and reenters the battlefield, causing it to enter with a +1/+1 counter due to its modular ability, and triggering The Ooze and Deadeye Navigator's soulbond ability.
  3. Resolve Deadeye Navigator's trigger, repairing it and Arcbound Worker
  4. Resolve The Ooze's trigger, creating a Mutagen token for each +1/+1 counter that was on Arcbound Worker when it left the battlefield.
  5. Activate Urza's first ability twice by tapping Arcbound Worker and a Mutagen, adding {U}{U}.
  6. Repeat.
