This is an amazing game and very addictive. There are a few things being worked on but for the most part its well worth the time to get into it!

Use of this code will get you 1 rare card and 100,000 rupies to get started with. Enter that code post tutorial to recieve your presants automatically.
A few tips for new players:
1) Evolve your cards to the max form before enhancing (usually 4 of the same cards needed to do this)
2) Use only fully evolved cards for enhancing others, you net more 'maturity' % this way as opposed to using the 4 base versions. (yes this costs a little more in rupies but its well worth it!)
3) Dont neglect your defense, nothing worse then trying to complete a treasure quest only to have others steal your treasure because your deck isn't able to repel attacks.
