4 rulings from Wizards of the Coast
- 18 February 2022If the enchanted permanent was attacking or blocking (or being attacked if it's a planeswalker) when Swift Reconfiguration becomes attached to it, that permanent is removed from combat.
- 18 February 2022The permanent keeps all of its abilities. Notably, if Swift Reconfiguration enchants a Vehicle, that Vehicle gains crew 5 in addition to any crew abilities it already had.
- 18 February 2022If Swift Reconfiguration becomes attached to a creature that is also an Equipment, that permanent becomes a Vehicle and loses the Equipment subtype. If it is attached to a creature, it becomes unattached from that creature.
- 18 February 2022If Swift Reconfiguration becomes attached to a creature that is also a planeswalker, that permanent loses its planeswalker type. Its controller may still activate its loyalty abilities as normal, but it can't be attacked and damage dealt to it doesn't remove loyalty counters.
