I finished Thronebreaker yesterday, so I've been digging in with Gwent now.
Handbuff Elves seem pretty decent - simple to build and easy to play, which is perfect for settling in and getting used to the new game and meta.
I'm not a pro and don't know what the better players think of the archetype, maybe it's considered bad, but it's been doing well for me so far. This is something I made quickly by mostly searching elf and boost in Scoia'tael deckbuilder lol.
Bronzes might need some changes here and there. I'm not using Hawker Smuggler, they are too expensive when they are just removed instantly. Aelirenn and Roach are just free points. Filavandrel seems solid - nothing overly impressive, but not bad either. He can be a 10 point leader with a very healthy amount of mulligans. 5 mulligans if you go first feels so good.
On my to do list is make a Draug/Specters NR deck, a Nilfgaard deck with cards like Cahir and Master of Disguise, and then something in Monsters.
