User blog comment:DaRoyalYoshi/I have a problem with the GTS/@comment-26084556-20150728072503

Unfortunately, here's the thing. A lot of people that use the GTS are so stupid that its not even funny. I did something similar, putting Cobalion in and asking for a Kingdra in return. Not that bad of a trade right? Because Cobalion is a legendary Pokemon. Well unfortunately more than 85% of people who use GTS put a Pokemon up, legendary or not, and ask for Pokemon that you literally can not send them even if you wanted to. Mew, Celebi, Jirachi, Shaymin, Manaphy, Victini, Diancie, and Hoopa are the most common that youll see being asked for, that fall into this catagory. The reason you can't trade them over GTS is because they are special pokemon, and there for can not be traded over GTS even if you have 10 of each. They are special because they cant be caught through normal gameplay and require you to get them from special events. What's even crazier is, while some people ask for these pokemon just to screw with people, most of that 85% dont even realize that they cant get those pokemon through GTS because they have never tried looking one up. So the reason nobody wants your Heatran is because most everybody is trying so hard to get these (literally) impossibly rare pokemon, that they could care less about a capturable Heatran.
