The guy who I got this type of deck from, from Reddit, got 22 wins this last weekend with it, so it's definitely viable. He got 19 last weekend too. I got 14 on both so that guy is definitely better than me haha. Here's his profile, you might need to look back on his history for his weekend Light deck since he changes it a lot: https://gudecks.com/meta/player-stats?userId=3693299
