Bottled Cloister

A protective lockbox for the hand, built around a trade nobody asks for anymore: a private draw step in exchange for total exposure on every opponent's turn. The first ability hides your cards from discard and hand attack by exiling them face down during enemy upkeeps; the second returns them and adds a card on your own. The result is an extra card per turn cycle bolted onto immunity from Mind Rot, Hymn to Tourach, and their kin. The cost is brutal and easy to overlook: while your hand sits in exile, you cannot react. Every instant, every counterspell, every flash creature is locked away during the exact window an opponent would want to force a response. The artifact converts a flexible hand into a sorcery-speed-only resource that exists only on your turn, the reason it tests better in theory than across an actual game where you want to hold up interaction. This is a symmetry-breaking draw engine that pays for its card advantage with a structural concession rather than a life total or a mana sink. The concession is your ability to interact during the half of the game that is not yours, and the design quietly assumes you are the kind of player content to do nothing on the opponent's turn anyway.
