Who owns a card you take control of with Sway, or steal with Heist, and where does it go when stunned?
The designer answered this directly in a 2023 post relaying the designers' rules.

The player who acquired the card from the Market owns it. A permanent steal, such as Thief's Heist, makes you the owner, while a temporary steal until end of turn does not. A card you control that is stunned, put into a hand or shuffled into a deck goes to its owner's pile instead.
