Disclosure: This is a free to play title with micro-transactions. I did not spend anything on it. (No idea where the loot crates came from).
The Queen is dead, the world fragmented, and treasure ripe for the taking. Join or create a group of Rangers plundering under a House banner as you collect cards to improve your deck. PvP only as of right now with special Twitch integration to provide viewers special objectives when watching a streamer. Complete objectives, win games and unlock loot crates in this CCG/tactical strategy hybrid reminiscent of Duelyst.
As with every other CCG, expect the difficulty spike to be massive due to the micro-transaction. People I fought were pretty even, but a few matches I watched before playing were heavily unbalanced. It is just the risk of the genre's business model. No campaign yet, but finding a match was quick and easy. Just wish there was a way to fight a CPU on the shards to avoid the long round times.
