I've dabbled in the game for about 3 hours and I like it a lot. Opinions, discussions, deck ideas, negative comments, memes, and queens ladies and gents.
I didn't like it. It has that feature that lets you play a card if you draw if from life loss, and I found it pretty unbalanced...
I find prophecy mechanic is really random and 100% luck based. I do like the game though. I can see it replacing Hearthstone mainly because it has better art and more MTG features.
Quite enjoying it, especially the arena drafts vs AI, is surely worth a try and the wait to see where it goes.
