Speed Boostin Pokémon Polished Crystal

Speed Boost is an ability that increases the Pokémon's Speed stat by one stage at the end of each turn. This means that as the battle progresses, a Pokémon with Speed Boost will become faster and faster, allowing it to outspeed more opponents over time. This ability is particularly useful for Pokémon that can take advantage of increased speed to strike first or evade attacks.
