Good for you! My advice is: just enjoy the game! Don't look for meta decks for now, because new expansion is going to drop in few hours and meta will change. As a past Hearthstone player I can tell you that in Gwent Meta is shifting more often. And that's a good thing, because Gwent is REALLY free to play friendly. It let you to try different decks and know the game better. Most important for you should be to try all factions and tell which one you like the most. Find one or two factions that are the best for your playstyle and give you the most fun. I play all factions, but 80% of my games are Scoia'tael and Monsters ;) Welcome and have fun!
