I think i'd like to see asking for legitimate levels. The gts is spammed with "zekrom 9
and under" or "reshiram 9 or under"
I'd also like to see an option where you could toggle if the pokemon you're looking for is
shiny.
Lastly, a button that would allow you to check what pokemon you could get in exchange for
a pokemon you have in your box. It would generate a list when told to.

You should be allowed to trade event pokemon because i have a shiny pichu but i don't
really want it

Try trading the pichu and if it doesnt work i guess you can do it with infared. The
improvements i'd like to see are not having to see the pokemon to request them as im sick
and tired of having to see galvantula or crustle in order to get them i even had to evolve
my ferroseed to get ferothorn. Also i would like to see what kings said about the shiny
toggling button but i dont agree with that list thing because the gts doesnt know what
everyone who plays this has so it wouldn't be able to but if it could it would be a very
long never ending list of lets say about 500 pokemon but also there should be a button to
toggle what nation you want it from because im tired of getting japanese if you want a
american pokemon but they only have the japanese type. Kind of like cereal wouldn't ya say
you want a certain one then boom they have the other kind.
