I just tried out this game over the weekend. Seems pretty interesting so far, though I don't think I've wrapped my head around most of the playstyles. I spent a lot of time rerolling over and over for some no-commitment gacha pulling fun to see if I would get anything good.
So far I've tried out Forest, Sword and Haven, but I think I still like Forest most (though maybe I should spend more time figuring out sword). I like the way you can spam cards and make cheap units way better than they normally are. Haven't tried out the other styles yet, though I don't know what's good for me. I got a few animated legendaries in my latest reroll, so I melted down a bunch of them and made a few Forest legendaries that seemed interesting to me, and have been playing through the story with it. Now that I have a better idea of how Forest cards work, I might go back and reroll again.
I just checked out the manasurge site linked earlier on this page, and realized that the deck I've been using has almost nothing in common with the top tier decks there lol.
I'm pretty lost, but having fun so far.
