Evasion and Accuracy Raising/Reduction moves are NOT working currently is my understanding (not coded). So moves like Double Team, Minimize, Sand Attack, Flash, Coil (supposed to raise Accuracy along with Attack/Defense), and the Compound Eyes Ability (in battle effect raising accuracy), etc. they all currently do nothing as it relates to accuracy/evasion.
Perhaps a mod can confirm or refute and clear this up just in case, but that is my understanding of Accuracy/Evasion moves currently.
