Or randomly pulling one from a pack...

You can pull promo cards from a booster?

Yes, but they are by chance, and are the rarest thing one could get, at least in one booster box one is guaranteed usually at least 2-3 SRUs, from 3 boxes, no promos are guaranteed in the packs unless they state so. I wouldn't try getting it from boosters. Yeah, a few people have them and still do on the forums, but I don't know many people, including myself, who would trade it at this point.
