Replication Specialist turns each artifact ETB into a free copy for

, so casting Silver Myr and Myr Galvanizer effectively doubles both engines on the spot. Lightning Greaves costs

to move between Myrs, which means the two Silver Myrs can tap for

each cycle, netting the

that Myr Galvanizer needs to untap them while feeding back into Replication Specialist's trigger cost. This runs in any mono-blue artifact shell — Urza, Lord High Artificer and Emry, Lurker of the Loch are the natural commanders for it.
