• Why can’t I see my cards? I *know* I’ve got more... •
Cards are shared between the nations of an account. If you play with more than one nation, you’ll need to be aware of this. If you have, say, 25 Human Archers that you’d like to use with both of your nations, the easiest solution is to modify a unit down to 0 (Don’t disband it! you’ll lose experience), and then create a unit in the other nation.
When you want to go back and play as the first nation, repeat the process in reverse.
