Having Gothitelle finally take down N's Zekrom, despite Gothitelle being far out-classed by Zekrom.
Granted, it did result in a draw...Gothitelle ended up getting done in by Zekrom, and with only a sliver of HP left, Zekrom got finished off by Future Sight immediately afterwards. Ah, if only Gothitelle's speed stat was better...then my pattern of Reflect+Future Sight+Psychic might have been more effective. (Not only that, but I did reset a few times before this happened.)
Not the smartest match-up, I know, but...yay?
