There has been many a time when I've Thunderbolted a Pokemon that has no business being Thunderbolted. I do have moments when all typing and reason go straight out of the window. Since I've never, in all the history of Pokemon used a Poison type, I'm still a little hazy as to their weaknesses. I'm actually thinking of giving Nidoqueen a try at the moment, so hopefully that will change XD
I'm also still rather bad at predicting my opponent, so accidents do happen, even when the opponents move would be extemely obvious to anyone else.
Got to mention my battle with LoN and Sophia, if only because it took me THREE attacks, and three Pokemon to realise what I was up against
