@z3ll I participated the second time and just finished the first round at #18 (wasnt it the first 17 go for the next round - next time I get it :D).
I want to share this battle. There we can see that you do not need a leveled up deck to win games - very important information for newer player like me:

Of course, team composition is the best advantage you can have, levels mostly give you an edge only (unless some cards become absurdly better when leveled up xD)
Just one thing, since this is the battle from #18, you should submit this fight on the next post. I will try to remember it, but the safest thing is just to comment this on the next post when it finally gets published. For some reason, the tournament didn't resolve yet so I don't have all the results and all I can do is wait now :(
