So hey, just re-started my old Pokemon Crystal game because I'm a poorfriend and can't afford a phone that will play GO.

I remember doing some hijinks with my old copy of Red to get just about any and all Pokemon I wanted (assuming I could catch them) by dicking around with trainers and dittos. Is there a similar technique for Crystal, Silver or Gold? Kinda want one of these pimpin' motherfuckers in my team but don't have any other way to get one. Also no, I don't have a gameshark.
