I love OHKO moves if I have them! I hate it if others have them though...
My Haxorus's Guillotine hit more during Audino grinding than Charizard's Inferno in the E4 battle with the ghost trainer! I know they have both very low chances of hitting, but Guillotine is 30% and seems to almost always hit and Charizard's Inferno is 50% and never seems to hit when I need it to!
But I agree... When a move that has a high accuracy rate misses, I get very angry and just wanna throw the pokemon in the day care and say "SCREW YOU!"
