[COLOR=Blue]I'm back.
Now, assuming that my Gastly is still frozen:
Gastly/Europe/1/Throw Master Ball (It says that on the first page under the different kinds of special balls. If I can't use it, then I'll use a Hyper Ball.)
Now, if Gastly has thawed:
Gastly/Europe/1/Sleep Powder (Until it falls asleep) (Then follow suit with either a Master Ball, and if I can't use it, Hyper Ball.)
