MTR 3.10 Sleeves

Players may use plastic card sleeves or other protective devices on cards.

If a player chooses to use card sleeves, all sleeves must be identical and all cards in his or her deck must be placed in the sleeves in an identical manner.

If the sleeves feature holograms or other similar markings, cards must be inserted into the sleeves so these markings appear only on the faces of the cards.

During a match, a player may request that a judge inspect an opponent’s card sleeves.

The judge may disallow the card sleeves if he or she believes they are marked, worn, or otherwise in a condition or of a design that interferes with shuffling or game play.

In the interest of efficiency, the judge may choose to delay any change of sleeves until the end of the match.

Competitive and Professional Rules Enforcement Level tournaments impose additional restrictions on sleeves.

Highly reflective backs are not allowed. Sleeves with hologram patterns across some or all of the sleeve front or back are not allowed.

Sleeves with artwork on their backs may be subjected to additional scrutiny, especially if there is no solid border around the edges.

When using sleeves on double-faced cards, sleeves must be completely opaque.

The Head Judge is the final authority on what sleeves are allowed.
