Sand Veilin Pokémon Polished Crystal

Sand Veil is an ability that increases the Pokémon's evasion by 20% during a Sandstorm. This makes it harder for opponents to land their moves on the Pokémon with Sand Veil when a Sandstorm is active. Additionally, Sand Veil provides immunity to the damage caused by Sandstorm, allowing the Pokémon to avoid taking damage from the weather condition altogether.
