We are able to purchase rare and mythic wildcards with real money. I had the idea of instead of relying on chance of getting common and uncommon wildcards through packs to craft our decks, I had the idea of common and uncommon wildcards be purchasable in the store... for example, 4 common wildcards pay 3,000 gold. 4 uncommon wildcards pay 5,000 gold. that way it makes it a little easier for us to finish crafting out decks instead of waiting and hoping to get wildcards to finish our decks that we are excited to try out.
