Some tips: Increase mainly stamina and defense early on. When you have around 60 stamina, it's a good idea to farm the cards in 2-2 to evolve them to what are known as "Feeder" cards. People buy sets of 9 of them for something like 3 cure water/1 holy powder. These are the unofficial items that are used to trade for rare cards. You can play this game without spending a cent if you're smart and do everything you can (post on twitter, support people, be smart about trades etc.)
