So far so good!!! A great introduction in to blockchain gaming. It feels as if the creators of this game are passionate about their product and don't want to dissapoint....
Fairly simple to get in to and transactions are fluid.
I managed to get a Legendary card within a few days which has a higher value than the money I put in to booster packs and starter fees.
A word of advice, be sure you learn the rules, especially regarding what monsters your summoner can play!
The game can be addictive so be careful!

I will update the review if need be.

Update:

I have just downgraded the rating of this game from 5* due to instability of the game and the spams that are easily easily exploited by the players for their desire to win no matter how, they generally have no honour or sense of fairness.
There is also a need to buy cards to compete with other players. It seems this is the only way to have a fair challenge, but these cards have become very expensive now.
However, if you don't play too competively and you don't mind being spammed every now and then then I highly recommend this game and give it 4 stars.
