Hello Arcturus777
Mantic is doing a testrun for such kind of product actually. They sell the unit cards for the Trident Realm warband as a webshop exclusive item. If it will sell well, they are thinking about to do it for all the other warbands also!?
So buy the Trident Realm pack to show your support maybe and wait a bit, to see what they are coming up with.
I would really appreciate it, if Mantic would sell all the unit cards for every faction as it's own product, like for the Trident Realm.
So fingers crossed and plug & pray
