Not at the moment but the option should come soon.
The game is not F2P, at least not as far as I know. The $20 price tag gets you the game and one starter. You CAN buy shards with real money, but everything in the game can be bought with gold earned from matches.
Looking at the website, they've hinted that buying in now will be cheaper than when they release the final version.
Welp, I'm just terrible at this game. Lost 2 easy ai matches and 3 easy trials as growth. How's that for an on-boarding experience? Went in to edit my deck a little and to my surprise, I can't b/c of the 50 card min. Is that really the case?
Might be balance related, but either way, I'm gonna put this game down for a while.
Decks require a minimum of 50 scrolls. If you don't have any other scrolls in your possession, then you can't alter your deck.
I play Energy, but Growth is one of the stronger starters. Can you post what kind of trouble you're having? Energy is an aggressive deck. Wolves, while weak, are an integral part of the starter deck. Early pressure with wolves, ramp up with Sisters of the Fox, Kinfolk, and the ATK boosting Idol (Altar?), then lay down your Wolf Brothers and big ass white direwolf doods.
You can trade units, but you should try to keep your unit-producing units alive. If you find yourself going on the defensive more than not, then you might not be playing aggressive enough.
Some of the easy trials are not easy. I think one of the devs said that Easy 2 was giving a lot of people trouble and that you should come back to it later once you've beefed up your deck. I haven't played a lot of Growth decks, but the ones I have are really nasty once you hit a kind of critical mass for your units.
