Even CWA doesn't have all his cards maxed. LOL

You don't have to be maxed to understand how the game works. Basically, there are only 3 cards that have a difference between max level and tournament level: freeze, rage and L-jack. So on tournaments, all the rules from the normal gameplay apply, except for the fact that overtime is 3 minutes instead of 1.

So, where I am going with this: you can even have your cards underleveled, the one thing that really matters is skill. I mean, look at my account: level 10 commons, a few level 8 rares and a some level 2 leggies. A lot of people in my trophy range have level 9 fireballs, which means they can 1-shot my musketeer, but that doesn't stop me. I am literraly 3 wins away from legendary arena, and I am pretty underleveled for it!
