I'm quite sure the answer to this question is "no", but I wanted to check: Smuggler's Copter, when crewed, does not trigger Soul Warden like abilities, correct?
A permanent, already on the battlefield, whose characteristics have merely changed (whether by "becom[ing] an artifact creature" due to the crew ability, or otherwise) doesn't "reenter the battlefield" this way (C.R. 110.1; review C.R. 702.122a). Thus, an enters-the-battlefield ability such as Soul Warden's doesn't trigger merely because a permanent already on the battlefield becomes a creature. In general, an object enters the battlefield if it formerly wasn't on the battlefield but is now there.
