These card can be used for a free2play blockland
Maybe the first card can cost 10$ and it have u the normal player power
and without 1 of the another cards u have a FREE ACCOUNT
THE FREE account maybe can have Limited power like:server with only 12 max player
some avatar and custom face are blocked
and a big text on the player name,FREE
The first card it give u the normal player power like who just buyed the game
and the other can give the player some special power?
I don't know but the free2play system can help blockand for get more player
Free version=multiplayer demo?
