Am I missing something here? You earn coins after you play a game, you use those coins to buy packs of cards, & in those cards are contract extension cards among others. My question is, how can you possibly keep contracts extended, when you only get one extension card per pack? Even buying the silver & gold packs it just seems there is really now way to keep up.
Now, I have a team with some good players, no contract extension cards, & my only real option is playing the low rated players on "pro" difficulty so I can actually earn a decent amount of points after each game.
