Mana needed: {5}{U}

U identity

Commander legal

The 2 combo pieces

What must be in place

You control at least one other artifact.

How to execute it

  1. Cast Masterful Replication by paying {5}{U}, causing each artifact you control to become a copy of Ugin's Nexus until end of turn.
  2. Put the original Ugin's Nexus and all other artifacts you control except one into exile due to the legend rule and their replacement effects, causing you to take that many extra turns after this one.

What the combo produces
