For players who refuse to spend real money, finding efficient ways to farm these resources is absolutely critical.
The developers intentionally make gold scarce to encourage microtransactions, but there are always workarounds.
Maximizing Daily Rewards
The simplest and most consistent way to earn gold is by completing every single daily task available.
Timing your chest unlocks so that you open the large ones while sleeping and the small ones during the day is a massive efficiency boost.
Don't push ladder if your chest slots are full.Know when your next magical or giant chest is arriving.Do not upgrade cards you don't use.
The Clan Economy
Joining an active, fifty-person clan is arguably the most lucrative decision a free-to-play user can make.
Even if your clan does not win first place, the participation rewards far exceed anything you can earn playing solo.
