[Set Comments]
<p>Xatu also has access to Baton Pass through Pokemon XD, turning her into a great Calm Mind passer. Her high Speed, access to Roost (which also temporarily removes Xatu's Electric-, Ice-, and Rock-type weakness), and her decent defenses also help. Psychic is useful as it provides good STAB, and gives Xatu something to do in case she gets Taunted. Substitute isn't really important to this set's success as Synchronize will (or should) discourage status users. The main idea of this set is to switch into a resisted attack, set up a boost or two with Calm Mind, and then escape with Baton Pass before the opponent has chance to hit Xatu.</p>
[Additional Comments]
<p>224 Speed EVs and a Timid nature allow Xatu to outrun positively natured Rotom, escaping before it has chance to hit Xatu with either of its STAB moves. Max HP makes Xatu more bulky, and helps her take hits much better. The remaining EVs are placed into Defense, which helps Xatu switch into physical attackers more easily, especially Fighting-types.</p>
<p>Recipients for the boosts are essential; you wouldn't want those boosts going to waste would you? Special attackers such as Milotic, Venusaur, and Moltres are all good choices as receivers as they are unable to boost their own Special Attack, though Moltres can raise its Speed with Agility. Be careful when using Moltres as it loses half its health upon switching into Stealth Rock, making a Rapid Spinner vital for success. Finally, while Octillery is a strange option, he can be an integral part of a Baton Pass chain; if you pass him some Speed and Special Attack, he'll be breaking through the opponent in no time. Octillery has the added benefit of Suction Cups, making it impossible for the opponent to phaze him out with Roar or Whirlwind.</p>
<p>As this set aims to gain as many stat boosts as possible, support from Reflect may be used to raise Xatu's Defense. Uxie, Alakazam, and Grumpig are all excellent options to set it up. Alternatively, Spiritomb and Mismagius may use Will-O-Wisp to cripple physical attackers and cut their Attack in half with a burn.</p>
