This is a fair point, and of course I am showing my wins, not my loses, but here is something to consider -
In the top tier of any league, Bronze1, Silver1 Gold1 etc - are the best people for that league, some of whom choose not to move up just to battle right where they have their cards and strategies all figured out. Silver3 can at times seem easier than Bronze1, and the same for Gold3 and Silver1.
Where ever I go, I don't win them all, but am able to get the wins I need to keep going.
I hope this helps!
Thanks for that clarification. It helps. I think I got it. I usually encounter these powerful cards when I was about to reach the top 100. It appears that there are strong teams guarding the gates. The highest rank I reached so far is 111 at Bronze I.
Top 100 in every league get special prizes - literally guardians!
