I tried the basic methods, but it didn't work. I thought maybe someone more experienced might help. In the game there is basically 3 value. Money, diamonds and pvp tokens. There are also bottles of experience to give the cards a level. There are many things that can be changed, but there is an anti-cheat system, although there is no mmo tag. Anyway, give it a try.
