I also believe that these cards are overpriced but I also believe we don't have to purchase max copies. With the current state of the game we find ourselves in this mindset of MAX DECK or BUST because of how cheap and very relevant the Chaos Legion set is. I believe that when rotation happens we will see a better spread of decks and leveled up cards because the price of rebellion is still sustained. Even though we don't have Leagues anymore, I see that ranked play will go back to something similar purely because of price. In THAT meta/environment this may not feel so rich because a partially leveled up card would make a difference.
