Confuse Ray. Supersonic misses half the time, but Confuse Ray always hits. I mean, come on, its hitting rate is 100%. No fair. -__- And Splash. Yes, SPLASH. When it's used by Magikarp. It just wastes your time killing useless fish. And Rest is annoying too, 'cause when the foe is sleeping, half the time it uses a berry or another item, and the other half of the time, all my moves miss and then it wakes up in one or two turns. >_>
