I once experimented with pulling for low RCL remote colony w/ one tow-truck and a few immobile creep types. The way Tigga described is the way I used, first creep had to find/had set a location where enough room was to pull (an exit tile w/ enough room), then move there. Next tick their in the next room and wait, the tick after they blink back to the other room next to the creep, issuing a pull toward the next empty exit tile. So that the puller moves to the new exit tile, and the pullee moves to the previous exit tile. Now that their both on the exit tile, the puller can move off but has to wait a tick while the pullee goes back between the rooms, once the pullee is back the puller can move it into the room.
As mentioned in the previous post, if the pullee has just one move part, it avoids alot of the waiting because it can navigate the border crossing easier.
I think there may have been another way mentioned in slack? But I don't recall.
