14.2. Card Sleeves
Card sleeves are allowed to be used at Pokémon Organized Play events, provided that they meet
the following requirements:
• All of the sleeves on a deck must be the same color, condition, size, and texture.
• The fronts of the sleeves are clear, clean, and free of designs, holograms, and emblems
that may obscure card information.
• The sleeves completely cover the entire card, leaving no portion sticking out of the open
end.
• The sleeves are not reflective enough to be used to clearly determine the faces of cards
that remain in the deck. A reasonable degree of glossy finish on a sleeve is acceptable,
but sleeves that create a mirror-like surface, where the card above it is clearly
distinguishable, are not permitted.
• Each card sleeve contains only one card.
• The use of sleeves with any form of pattern or artwork on the back of the sleeve is strictly
prohibited at all Premier Events, unless the sleeve is an official Pokémon sleeve, where
the color along all four edges of the sleeve is identical.
• The Head Judge of a non-Premier Event has the final say over whether or not art-backed
sleeves may be used at that event. Inappropriate sleeve images (as determined by the
Head Judge) are strictly prohibited.
The Head Judge has the final say regarding whether a player’s card sleeves may be used in an
event.
Players should keep in mind that card sleeves are not a requirement at Pokémon Organized Play
tournaments or events. Should a judge inform a player that their sleeves may not be used at an
event, the player has the option of replacing the sleeves with more suitable sleeves, or playing
without sleeves.
