Really quite addicting and fun to play, but with a few heavy issues. The first is that the in game purchases of gold are seriously over priced for what you would get in game - this is more just a comment as it actually keeps the game from becoming pay to win. The real issues are with translation and layout. Most of the flavor text on cards makes little to no sense with most text cut off. Cards abilities use "and" instead of "or" when giving attributes, and many of the in game activities have poorly written instructions. On top of all this its very easy to accidentally spend gold as some buttons have 1 touch systems, while others have a gate to make sure you want to spend gold.
