Rotom is a really weak sort of legendary. You can only get it in Pokemon diamond and pearl. So it is sort of not possible to get it in the wild in soul silver. You can get him in the GTS, if you're lucky. Also if you have a friend that has rotom, rotom can breed with a ditto so you can get a rotom egg. Then you and your friend will both have one.
