As Gs135790 said, Never save as JPG.
Oh, and the GS pokemon, um no. Please, If you like the design, you could ask somebody to revamp it for you.
It dosen't have much effort put into it, like, theres no name, Names of pokemon, badges, The backround is neat, Did you make it?
Anyway, The white corners, please make a border or something.
Do all this stuff and that card will be great. Hope you follow it.
