That is essentially the strategy called PHaze. PHaze stands for Pseudo-Haze. Haze is a move that cancel all stats changes, so Pseudo-Haze has exactly the same objective, but in a different manner. Pseudo-Haze is the use of Whirlwind, Dragon Tail, Roar or moves like that to force the opponent to switch and wast their stats boost. Common users are Hippodown, Tankchomp or some defensive Swamperts variants.
