Sand Attack is a move used by various Pokémon in battles. When a Pokémon uses Sand Attack, it throws sand at its opponent, which lowers the opponent's accuracy. This makes it harder for the opponent to hit their attacks, giving the user a strategic advantage. The move is often associated with ground-type Pokémon, but it can be learned by several others as well. Sand Attack is particularly useful in competitive battles, as it can disrupt an opponent's strategy and create opportunities for the user to gain the upper hand.
