There are just 3 moves that increase evasion. They are...
Acupressure: Acupressure raises a random stat - Attack, Defence,
Speed, Special Attack, Special Defence, Accuracy or Evasion - by two
stages. It will always choose a stat that is not already maximized.
Double Team: Double Team raises the user's Evasiveness by one stage,
thus making the user more difficult to hit.
Minimize: Minimize raises the user's Evasion by two stages, thus
making the user more difficult to hit. Stats can be raised to a
maximum of +6 stages each.
The moves Stomp and Steamroller hit with double power against a
Pokemon that has used Minimize.
Hope I helped out! PX ;}
