One idea that I had was that of you got to arena 8, and got a bowler, then you go back to arena 7, the card is grayed out. When you tap it, it says you need to go to arena 8 or higher to use this card.

In my eyes, this would prevent a lot of the unfairness of the higher arenas, and would make the game more fair as everyone had a chance to get those cards
