Hearthstone: The Witchwood
Top Critic Average

So that's my recommendation. Play and enjoy the Monster Hunt mode, but stick to the Arena and Tavern Brawls when playing against others if you don't want to open your wallet. I still enjoy playing this game, but the busted meta means I'm enjoying playing against other people less and less.
