I like the idea in general, but one thing is bugging me that would be very easy to change:
Maxed cards compulsory in Champs level needs to be changed to maxed Archons.

It takes time to max reward and “extra” cards, making them unplayable in the meantime. Plus, some cards are strategically better at a lower level.

When/if these changes are made, I’ll vote FOR. Until then I’m abstaining from voting.
