I have a question regarding Mystifying Maze. If my opponent has a creature that I own, let's say by way of vedalken shackles or donate, if I use Mystifying Maze on them will the creature return to my control when it comes back into play at the end of the turn? I would think it would, because Mystifying Maze says "owner".
Yes, the card will enter the battlefield under its owner's control, regardless of who last controlled the creature before it was exiled with Mystifying Maze. (But note that even if Mystifying Maze omitted "under its owner's control", so that the card would enter under your control since you activated Mystifying Maze's ability [C.R. 110.2a, 608.2c], it still wouldn't matter who last controlled the creature before being exiled [C.R. 400.7].)
