I think the SARUTOBICARD is a nice move from the team marketing with a Japanese Game Studio!
Hope to see more of these partnerships coming up in the future, should do great to promote SoG.
HaHa - Think Sarutobi is already Out Of Stock
I see 52 cards in Swapbot and 100 on Issuer vallet. Maybe are temp stored also somewhere else. But 600 cards is not that much. And if 450 were sold, that was really good. Main reason i see is in price. Sarutobi cost 60 BitCrystals few days after release. Half year ago, price escalated so fast that reached 800 BiCrystals in few hours. And one of those cards, BearWhale was issued in 3000 cards.
