Attacks 2-5 times in one turn; if one of these attacks breaks a target's Substitute, the target will take damage for the rest of the hits. This move has a 3/8 chance to hit twice, a 3/8 chance to hit three times, a 1/8 chance to hit four times and a 1/8 chance to hit five times. If the user of this move has Skill Link, this move will always strike five times.
One of the user's stats, including Accuracy or Evasion, is randomly selected and boosted by 2 stages. User can also select its partner in 2v2 battles to randomly boost one of its stats.
Opponents will be poisoned as they enter the field until they use Rapid Spin. One layer inflicts regular poison while two layers inflict Toxic; switching in a non-Flying-type Poison Pokemon without Levitate will remove any layers. Flying-type and Levitate Pokemon are only affected if they switch in while Gravity is in effect, Iron Ball is their held item or they are receiving a Baton PassedIngrain; Steel-type Pokemon and Pokemon who enter with Baton PassedSubstitutes are not affected.
If the target switches out on the current turn, this move strikes with doubled power before the switch. Baton Passers still escape safely. When a faster Pokemon uses Pursuit against a U-Turner, the U-Turner is hit for normal damage; when a slower Pokemon uses Pursuit against a U-Turner, the U-Turner makes its attack, then is hit by Pursuit for double power, and switches out.
Almost always goes last; in trainer battles, the target is switched out for a random member of its team. Escapes from wild battles. Has no effect if the target has Suction Cups or used Ingrain.
