A good Kout deck rarely dies because of the game itself. It dies because of everything around the game: the humidity of a Kuwait summer, the dry desert air at a winter camp, and a table nobody wipes down. A few minutes of care is enough to keep a deck straight, clean and fair for years instead of a single season.
Card stock absorbs moisture. In humid weather the deck swells, feels heavy and starts to bow, so shuffling turns into wrestling. Dry desert air does the opposite: the paper loses moisture, becomes brittle and cracks along the edges. Dust is the third problem, because grit slides between the cards, roughens the edges and leaves grey lines across the faces over time.
Rough shuffling wears out a deck faster than anything else, especially if someone at the table likes to slam the pack down to make a point. A medium, relaxed shuffle is all Kout needs, and cards should be dealt off the top rather than dragged from the corners. Hold the pack in the middle or by the base, keep the wrist movement soft, and if one of your regulars slaps the deck after a big hand, that habit has to go.
The best home for a deck is a rigid box, wood or thick plastic, with an internal divider and a band or clip that stops the cards sliding around. Store it in a cupboard in the room where you play, away from heat, moisture and direct sun: not in the car, not in a damp store room, and not in a sealed plastic bag where moisture collects and stays.
The signs are easy to spot: curled corners, white lines on the backs, oil stains, or cards that no longer feel the same thickness. The real problem is not how it looks. Once one card's back carries a mark, its owner knows something nobody else at the table knows, and that quietly breaks fairness, turning a hand of skill into a hand of luck.
Serious players keep a fresh spare deck in the box and bring it out for important sessions and tournaments, especially long ones or when the main deck has seen a lot of nights. The simplest routine is rotation: keep two or three decks in service, give each one a set number of sessions, then let it rest. That way no single deck becomes known to your group, and every deck wears slowly and evenly.
It also helps to know how much each deck has actually played. The Kout Score app helps you calculate and track the scores of your Kout sessions — it is available for free on Google Play, and the session history is a handy way to see how many nights each deck has behind it.
