Forged in the Barrens Cards List & Guide
It's at like 43% on Hsreplay, which means that if you play it you'll go DOWN in rank, rather than up. Yet, every mage I face plays it.
Is there something I'm missing? You should play what's fun, but when every player plays the same type of deck, there's normally a reason, but it's certainly not the win rate.
My guess, while not knowing what deck you are talking about since I play Wild, is that it's a good deck that a LOT of bad players are playing right Now. Therefore the low win rate?
