This game has gotten quite popular it seems - a lot of MtG streamers stream it occasionally, and there are often channels with >1k viewers. I decided to give it a try, and it's pretty good. Uniquely among autobattlers, there's no timer, which means you can always do something else in between runs (like interact with viewers). Other strengths are that layout is not trivial, the discount system (occasionally some pieces will get a 50% discount) incentivizes different playstyles, and there's literally one patch a week. Weaknesses are that it's not obvious why you win or lose (as opposed to SBB where you can clearly see some units carrying), and I personally find it difficult to optimize a board since it's not clear how much mana/stamina etc regen I have.

Is anyone else playing this?
