Writing about games that use blockchain technology is fun, but at the same time an arduous task because of the elements that must be evaluated, in my opinion the following parameters should be taken into account: graphic design, if it is entertaining, opinions on the network about the game, theme of the game, complexity, cost to play, equipment needed or requirements, if it is very heavy and something important for many, what do I gain by playing it?
Every day new ones appear or are being developed, I found this one to evaluate it, it is a game similar to many already evaluated, collectible cards in which only you are the owner of each digital asset that are cards, the game is developed within the ethereum blockchain, it is available only on mobile operating systems IOs and Android, the download is free but the game assets you must purchase them, they are cards that fulfill specific functions of characters, spells, you can only have 3 spells, battle cards.
It should be noted that when you download the game you have a welcome bonus that you can exchange for any card in the mining section, you must add the metamask wallet to store the ethereum available for purchases, new cards can be purchased in the mining section and directly in the game in the card sale section. You can also buy them directly from another user, as active cards can be bought and traded in and out of the game. In the game there is a trading section for it, something good is that you can play with your cards in other games developed by the same company, that is a not very common feature, there are cards that are limited and have different functions and values. In the game you level up, to be able to trade with the cards you must have reached the silver level.
The web portal is very basic, only vague information, it should have more information about the game, for example the tutorial should be on the web and it is not, the tutorial is in the game already downloaded, some parts of the game have not yet been translated into English, they are in their native Japanese language, country where the game was developed.
As long as you don't have the card for sale you will have it available in your deck, from where you can use it in battles. The battle is done with another player online, and from your deck you must have the strategy to win the game and select the right card.
In short I recommend this game especially to those people who like the card game mode, but I recommend to see the tutorial if you want to be successful in the game.
