Curious about everyone's favorites/regrets considering we have limited resources short to mid-term, especially as I'm still building my collection. 🙂 These should be cards you went out of your way to craft and not ones you pulled from kegs. They don't have to be 'good'/meta cards, as long as you found them fun enough to play. Bonus points for cards you regret milling! Even if you've a veteran player who had since completed your collection, I would still appreciate your experience early on (and I'm sure others would too).
Favorite Crafts: Alzur (just a ridiculously fun card that can fit in a lot of decks), Cahir (great counter to many decks, even if dead in some match-ups), Yennefer's Invo (sheer utility), Saskia (had a lot of fun with harmony despite it not being good, and still hope she gets buffed someday), Ramon Tryconnel (can't have a soldier deck without him!)
Regret Crafts: Uma's Curse (not as much fun or as borderline useful as I hoped, even with Alzur), Regis Bloodlust (even playing him during journey-time, he's way too awful to be a fun-of), all the cards that were later added to the new player trees XO
Regret Milling: Bekker's Dark Mirror (fun in some decks), Syanna (never found a home for her and know she's not good, but wish I played around with her more / still had her to play around with), Saov Ainmhi'dh (did it before the buff).
