The trailer looks pretty sweet. It looks like card games are going to be the first game type to really take off on the blockchain. It makes sense as cards a perfect example of a digital item that could be made scarce and have value. And when you win battles you can earn new cards which give you a new reason to play. You will need to make new boarders and have special cards to make them higher in value but the trading and collecting of cards has already proven to be successful off of the chain with game like Hearthstone.

Skyweaver is being made by Horizon studies who is actually owned by the co-founder of Reddit. They raised $3.75 million dollars and you can see where some of that money went in the prouction of this game.

 The promise is that you can earn and trade your cards. The trailer doesn't say anything about selling but I am guessing that is allowed too if I can trade them. If that is the cause I will be giving this a try when it comes out and see if you can make any money off of earning and doing well. 

The cards themselves have a cost, life and attack. This is the thing you are used to if you played any game like Hearthstone. I see there are leaders too so if you lower their life you probably win the battle. I am excited to see a leaderboard in the trailer could be a fun ranked mode on the blockchain where you can earn good rewards for placing.

It is too early to tell if this will do well or not but it looks like it is worth a try. Here is the early sign up if you are interested:
