Item Clause is a rule used in some battle facilities and competitive formats that prevents two Pokémon on the same team from holding the same item. It is not a universal Pokémon rule; many formats allow duplicate items, while others do not. The clause encourages varied item choices and can affect team building significantly. Before preparing a team, read the rules of the exact format, tournament, online ladder, or in-game facility. A moveset that is legal in casual battles may be illegal under a specific clause. Format rules should always be checked alongside generation, level limits, and banned Pokémon lists.
