With my stars from the alt Club Nintendo accounts I have, I've managed to order 6 sets of 2 Kid Icarus AR Card packs. Which means a total of 12 packs and a total of 72 cards.
Plus the 6 I got with the game itself and it comes to a total of 78. You may think I'm a bit overkill, but I never buy anything with the stars on my alt accounts and there's not really anything worth buying at 1000 or so stars. So yeah.
My main account is what I use to buy worthwhile items. Like the SNES Classic Controller which I'm currently waiting for.
