Completely unbalanced and luck based: whoever plays the yellow artifact ("steal") can win with 1 card in 2 turns unless you have something with "ranged" or equally broken. There's no point in playing anything different than the yellow artifact.

All mechanics related to spaceships are confusing or half baked (there's fuel but I couldn't find any way to refuel your ships).
Deckbuilding is extremely slow as it relies pretty much entirely on the marketplace.

Overall, it seems an incomplete experience compared to other card games. I'd rather stick with games where I can create more cards and the meta isn't set by devs (I.E: Ariokan)
