At the beginning of your upkeep, Moonring Mirror asks whether or not you want to switch the cards in your hand with the cards exiled under Moonring Mirror. If you click yes, that happens. If you click no, it doesn't.
What is the actual behaviour of the card?
At the beginning of your upkeep, Moonring Mirror asks whether or not you want to switch the cards in your hand with the cards exiled under Moonring Mirror. If you click yes, that happens and then the upkeep trigger is still on the stack and your opponent has priority. After the trigger resolves again, you are asked the question again. This is advantageous because you can look at the face-down cards exiled under Moonring Mirror and then switch them back with the cards that were originally in your hand, which eliminates the risk of exiling your hand for worse cards that are under Moonring Mirror. If you click no, the trigger goes away like it normally does.
