I used to love this game, but no developer updates in 3 years, no new units or rebalancing. At a certain point, unless you spend over $150 for each of your possible setups, you WILL lose. Could've been great, frustrating at this point. You never get the cards you need, and I'm not exaggerating. You have to spend a month or so cloning to get anywhere. I had like $50 worth of gems I'd been saving, gone just to be remotely competitive. Sad really.
