If I have a creature I own with Assault Suit equipped, then give control of that creature to my opponent during their upkeep, if they destroy assault suit (such as with Abrade) does the creature return to my control immediately, at the end of their turn, or never? Does this answer change if my opponent moves Assault Suit to another creature using Magnetic Theft?
My hunch is that the effect of Assault Suit a continuous effect that is just applied to the creature at the beginning of my opponent's upkeep, and therefore is unaffected by the current status of Assault Suit (just like how like an Act of Treason effect). But confirmation would be useful
