This has probably been stated before but the Wild Hunt should probably be their own faction. Most of their cards aren't in the best of shape right now so it may be logical to rework them into a new set. I know this going against OG gwent somewhat but the wild hunt aren't really monsters anyway. Cards like Caranthir etc could simply have their abilities transferred to new monster cards if necessary. Just a suggestion but I think pure wild hunt decks could open up interesting new keywords etc based on the white chill (I know white frost already does exist as a card but it is basically never played) or some kind of regicide archetype (where you have a designated king and benefit somehow from killing it) etc. Just a thought for some more diversity.
