I’m having fun too. I just finished a couple of the ‘alpha’ puzzles.
Have any of you tried the player-made decks of the week? What a neat feature that is! You can take these decks into constructed (PvE or PvP). In my one game with the “sacrifice” deck, I won easily, although that’s not a playstyle I normally prefer. I won two out of three using the “arena” deck, but I had much more trouble with it. Its central theme is supposedly using the Arena to have your minions duke it out with theirs, but I haven’t really gotten that working for me.
I also like that there are so many PvE options, including a draft mode – and they all bring rewards, all the time. I’ve played about a half-dozen PvE gauntlets, going the distance in all but one of them. OK, the AI is not as good as a player would be, and it occasionally makes dumb mistakes, but mostly it plays well enough.
I, um, actually haven’t tried PvP at ALL. In Hearthstone, I’d get very stressed out playing actual humans. Here, I don’t have to. So maybe I don’t care if the servers are mostly empty. Although judging from the chatter in the Discord, there are people playing online.
