HI. i am one of the workers here so here is what i can do...
My specialty is trainer cards but i also do recolores
in the meanwhile i use these templates but hopefully will adopt some others soon:
The simple one
The multi-badge one
by now i did 2 types of TC: Themes and regular ones...
Themes
ice theme
fire theme
flying theme
Regular
if you want a trainer card here is how you should enter the details:
Template-which one do you want?
Name-that should be desplayed in the TC as your name
Pokemon-if shiney write it (for example shiney pikachu)
Trainer sprite- write name and/or add the sprite itself
Background- write how you want it or provide your own background
Badges- which set/s you want
Pokemon behind trainer- optionel
Theme- optionel as well
as far as recolores here are some of the ones i did:
ok so that's should be it if you want a trainer card or a recolor from me just reqeust and i'll do my best do make it just like you wanted it...
