CONGRATS !!!
I search for my name in that leaderboard but I cant find it. Maybe toooooo high up
But now, with that card, you can buy A LOT of cards.
I am thinking - to buy that card you need OR buy boosterpacks . I am not sure what is best. The price at market at rare card is even high.... I think I go for 12 packs for 100 000 starbits.
