I just want to know what people think is the best trade evolution Pokemon that originate from gen 1 that would be strongest or coolest to use in gen 3 emerald or a future FR/LG playthrough, as I'd love to all of the different opinions and inevitable disagreements to see what holds something back or makes it excel, both in a playthrough and battle frontier or just flat out casual use (not competitively, but something I could use with no restrictions either, like any tm, hm, or move tutor access.)
