What is the purpose of placing a minimum card level on higher leagues? I'm not for or against it at this point. I would just like to understand the thinking behind it. There are some very good cards that are hard to max and it seems a little unfair to not even allow them to be played. For example, the Yaba card and/or Grix are two cards that have their uses in Champion that are very difficult/expensive to max out. Seems a little over the top to force people who have already spent tens of thousands of dollars to spend another couple thousand (or more) just to be able to play them. This goes for some of the past Rewards cards as well. Especially Rebellion where you didn't have the current reward chests like you do with CA.

Seems to me Champion should be an "Open" League where all of your cards are available, regardless of level. You will be playing against mostly maxed decks anyway, so its to your own disadvantage to play less than maxed cards. But at least you should have the option while you're continuing to build your deck.
