ETA: Try three did it. Let me show you Hiidoran~~ He's my new box-friend.
So now I have a Modest Heatran and a Calm Cresselia in the event that I ever try going into competitive battling. Happily, neither fall in the ubers category, but unfortunately one of my main party members does horribly in standard and can only function in ubers. Poor Shedinja: flying, dark, fire, ghost, and rock (rock especially) are so common. Plus Sandstorm. Killed by Tyranitar and Hippowdon without even a chance at survival.
