I have three Exo guardians. I made the choice without knowing that the Human and Awoken cards can't be unlocked without starting a guardian of those races. Is there another method to get the cards for the other races in the grimoire, so that i don't have to scrap one of my guardians? They aren't cards that require some difficult task to be completed, (like the lighthouse), so I don't think it should be an issue to add promo codes for them, or something of that nature. Please advise.
