It's a bit rough around the edges, if they keep supporting the game and you like card games, it should be worth it in the long run. However, the game pacing could use some tuning, it devolves into bigger=better rather fast and you can fight for 20 rounds without scratching each others HP. They could also use mulligan mechanic at the start. Card advantage is a bit undervalued since you can discard 1/draw 2 once a turn or discard 1/add 1 "land". I feel like the game gets grindy pretty fast, because you get your starter deck and everything after that needs to be bought and you are looking at 3 challenges per booster, which take like 20? minutes each, assuming you don't run into a deck that counters yours. Since you can only play stuff during your turn, the game has obviously nowhere near the complexity of MtG.
