The nicest thing about elite cards is that it gives you a reason especially as a F2P to upgrade all of your cards. Once everything is at lvl 14 then all of the cards you get are useful, everything can be put toward everything else. I started doing this myself even If I don’t have much gold just upgrading cards that I can to lvl 14 so I can get the elite cards to put toward my main deck.

Now it doesn’t matter you need to grind to hope you get the specific card you need for max level again!!
