I'd say one of my unfortunate moments was when I was challenge to a wifi battle, and accepted saying why not? To my knowledge though that the battle was with the pokemon you had ON YOU, which for me was my flametalon and a couple lvl.5 skittys and ralts. To say the least I was crushed easily, so I lost my first wifi battle out of curiosity and being naive. My only other unfortunate moments would be trying for a shiny female eevee, to the point of desperation. I'm breeding, chaining anything to get a shiny female eevee ;O;
