Simple, looks great and addictive game.
The game lets you collect cards in many different ways, such as: questing, completing treasures collections, buying packs with points or with real money (really optional) and special cards from events that will always keep you busy.
You can collect many cards and even evolve them (to change a bit their look and increase their power) or enhance them in order to increase their level and power.
The cards design is wonderful, anime style, getting new cards is always satisfies, the game is easy to understand, you can create or join other orders in the game (it's like a guild), it looks good and I find it fun and very addictive.
If you want to get 100,000 Rupies (it's a lot for beginners) and a free Rare Card (you can't simply get this card by just playing the game) already on your first day, just enter this "Referral Code": htm92279
at the end of the tutorial (you won't be able to add this code later).
Download and Enjoy this awesome Game!
