Moonring Mirror is a unique card from Champions of Kamigawa that aims to provide an amount of card advantage. By itself, Moonring Mirror is a slow draw engine, similar to Bomat Courier. No player is allowed to look at the cards exiled by Moonring Mirror, so it can also make tutors more difficult to use if the desired card is exiled instead of being in the deck. Conversely, if the controller of Moonring Mirror searches their library, they will have an idea of what cards are currently exiled.
There are many possible homes for this card. It can give colors such as white and red access to additional card draw. It can also increase the potency of draw spells in blue and black decks. A great example of this would be casting a Blue Sun’s Zenith on your opponent’s end step, just before your turn. Even though you’ve just drawn X cards, none of them are particularly helpful at the moment. Thankfully, Moonring Mirror also exiled X cards from your library face down. On your upkeep, you can swap out your hand for the cards in exile, effectively giving you an entire second hand.
The longer Moonring Mirror stays on the battlefield, the longer it is able to accrue value for its controller. However, the mirror also comes with a few major drawbacks. Once in play, Moonring Mirror will exile a card for every card its controller draws. This is not an optional trigger, which ties into the second, much larger problem. When Moonring Mirror is destroyed, the exiled cards remain face down and are inaccessible to their owner for the rest of the game.
A card like Moonring Mirror will need protection. Cards such as Slobad, Goblin Tinkerer and Padeem, Consul of Innovation keep Moonring Mirror safe throughout the course of the game. Additionally, being 5 mana means that the Mirror may sometimes be the highest CMC artifact on the battlefield, enabling Padeem’s bonus draw.
 Another use of Moonring Mirror is to protect certain cards until they are useful. By swapping out your hand on the first upkeep after the Mirror is in play, you can keep your desired cards safe from hand disruption until you want them. This can prove especially potent if you find yourself with a combo in hand that you don’t have the mana to play yet. Simply set it aside for and replace it with the new hand Moonring Mirror accumulated.
Moonring Mirror functions very similar to cards such as Alhammeret’s Archive.
It is important to note, however, that Alhammeret’s Archive does not provide an extra draw for the regular card drawn for turn. Additionally, Moonring Mirror circumvents opposing cards that interact with drawing cards, namely Consecration Sphinx and Notion Thief.
 Moonring Mirror can find a home in many different decks. Here are some examples:
Massive Draw power decks: Arjun, the Shifting Flame, Prime Speaker Zeganna,
Decks which Empty their Hands quickly: Malfegor, Azusa, Lost but Seeking,
Decks which crave card advantage: Slobad, Goblin Tinkerer, Eight-and-a-Half-Tails
