Not sure if this is a bug or not, but I think it is: Opponent had
Tidehollow Sculler in play, it had exiled
Daze earlier. Opponent plays
Restoration Angel, the blink ability targeting Sculler. When Angel's ability finishes resolving, opponent puts the two
Tidehollow Sculler triggers on the stack, first the exile a card, second the returning an exile card (this one resolves first). However, the
Daze is not returned to my hand. He ends up getting another card from me without having to return the first one. Is this a bug like I think or is it a good combo?
