>>5007610Apparently if you place highly in a pvp season you get a lot of ultra rare cards. So the competition is high. And to upgrade a card you need multiples of it to combine with itself. I think it's 5?
Just getting one card costs more than a luxury car in some cases. But if you place first you get all five of the newest, hottest card. So.
Anyway, this is all going by memory of what some anon said. Basically neets with assloads of disposable income somehow (sons of rich businessmen probably, or Arab princes or some shit) whale like motherfuckers to compete for ninja titties.
