It's slow, but using ATK and DEF arcanas are the only way to max cards. If you want to save some gold, you can start maxing them when your card is level 1. You can also save some time by rasing both attack and defense at the same time. Other than the +500 arcanas, there's nothing else you can do to speed up the process.
