Supposedly all Pokemon on the GTS in B/W are legit right? I just got a shiny Giratina lvl 33 in an Ultra Ball...and its from Sinnoh. Call me crazy, there's no place to get a lvl 33 Giratina there...

There is, an event Arceus was given out over wifi iirc anyway, this Arceus let's you go to the Sinjoh ruins, (Which is ruins between Sinnoh and Johto) with the Arceus in your party, you can choose to acquire one of the Sinnoh trio at Level 1 (Giratina, Dialga, Palkia)
Note : It was given out during HG/SS
