When choosing a video game it is necessary to consider the following parameters: Chain of blocks in which it operates, quality of the game and innovations that it presents, entertaining and lucrative, I would also say very important evolution of the game to the passage of time, that it is updated to improve and to include characteristics to attract new players.
And to be frank this game only counts that it is based on a good chain of blocks like the EOS, which is apt for fast games and other kindnesses that the chain EOS offers.
The game if you know some traditional game of card collection in which you must create creatures, develop it and compete with it, you know the game, is very basic locked in that theme, does not offer any innovation that attracts you, on the other hand seems to have remained static in time and this is a very common complaint to the point that it seems to have fewer and fewer followers.
Personally I do not consider it a good option to recommend there are many more options on the market, more entertaining and lucrative
