i don't care about authenticity either as long as they work! i don't have many fan made cards though- just a set of sanrio ones because those are the hardest to get. considering getting some fan made WA villager cards, but i'm so broke ;;
I went for authenticity because I started waay back when the 1-4 series only worked with HHD and no one knew the WA update for New Leaf was coming. lmao, I remember getting Fauna's card for like $1.50! Sooo much easier back then! But if it weren't for that I wouldn't care for authenticity either.
