Encroaching Mycosynth makes Timestream Navigator an artifact, letting Drafna, Founder of Lat-Nam copy it with his

tap ability while the original returns to hand via his

ability. Swiftfoot Boots grant haste to Drafna on the first setup turn and then shift to the Navigator token so it can activate immediately for

. The city's blessing is trivially met once both Navigators enter simultaneously, and the lock is clean — the token goes to library, you take the extra turn, and the loop resets.

How it works

Activate Drafna's first ability by paying , returning the nontoken Timestream Navigator from the battlefield to your hand.
Activate Swiftfoot Boots' equip ability by paying , attaching it to the Timestream Navigator token.
Activate the Timestream Navigator token by paying , tapping it and putting it on the bottom of your library, causing you to take an extra turn after this one.

Result

Infinite turns; Lock

Cheaper, tighter, alternate lines

Any haste enabler substitutes for Swiftfoot Boots if Drafna needs to act at sorcery speed the turn he arrives — Lightning Greaves is the tightest drop-in. Without Encroaching Mycosynth there is no line; it is load-bearing, so Fabricate or Whir of Invention deserve a slot to find it. Teferi's Ageless Insight or a Laboratory Maniac variant closes games faster if the lock needs a win condition beyond the extra turns themselves.
