I read the wiki page (before posting here), and it shows :

“After you earn your first scoop, you will automatically be thrown into a bracket with other Forumwarz players. The first week you will be placed in a random bracket but in subsequent weeks you’ll find yourself in a bracket with player who have a similar number of medals (to keep things competitive).”

... OK …

But how do I even know in which bracket I am? And I still don’t manage to buy cards… The wiki says : “You can purchase a Domination Card in exchange for 4 scoops of any Flava”, but where do I click??

thx
