Alright, 2 things to unpack here.
1) Some players played before certain units were unlocked in higher tiers. So they could get these units earlier than players now can. This caused some balance issues, and that is why they are now locked as they are. But you can't just take units away from players that earned them legit. So instead, these players no longer get MORE cards for those units, but can still play them in their current levels.
2) Challenge battles for LEVELS use a hidden mechanic of comparing your average unit levels to the league cap. If your average is not within 3 levels of this cap, you no longer qualify for a LEVEL based challenge battle.
Sorry you had to go through that, don't take it personally, and keep on being awesome! Hope this helps!
