"Favorite of the original "trade" quartet?"

I consider these four to be a quartet because, well, they're the original ones that involve with trading in order for their middle stages to evolve into them.Trading obviously sucks, though. I have never actually bothered to attempt trading myself (lmao I actually once had a used copy of FireRed that had them). But regardless, who's your favorite out of these four? Since Gengar is basically one of my favorite pokemon ever, that one gets my vote.View Poll via /r/pokemon https://ift.tt/33jPPyg
