Attack Doesn't Work

[Former user]

My Raichu's Electro Ball does not work against Sableyes inside of Cyan Cavern.

When i use it, it says my Raichu uses it twice, no attack animations go off then it goes to the sableye's turn.

My Pikachu has this same issue. Sometimes it works, most of the time it doesn't. I have video of it here: https://www.dropbox.com/s/15adgtdtk12oh6g/electro_ball_derp.flv?dl=0
