Simple to pick up but allows you to really get involved with deckbuilding and items that change the gameplay giving great replayability.
Moments that a plan(or some draw luck) pays off in combat feel great from something like lining up a bunch of crits with a scry to drawing just the right combo of shield cards to live through being hit into the next round.
It has a clean and thematic UI with some nice conveniences.
I'm excited to see where the story goes in the future, along with any new items and card types.
