One suggestion I have is maybe switching out those minotaurs for some more 3*s. I imagine if you are lasting to mid game then you will either already be winning or the minotaur likely wouldn't be enough to save you.
I'd consider switching out to Marsh Walker asap. It is widely considered the best 1* right now when paired with flourish and shieldbearer. If you can flip some of your unused earned cards: Bronze Gate, Underbrush Board, Ornery goat, jaguar Staffs would be great buys.
Thanks! I am considering it as well. Marsh Walkers... unfortunately I wasn't lucky enough to pull at even one, in future new players will have easier and cheaper acces to core cards because of forge reopening. But right now few options we have are:
After getting 2 epic DO packs for last weekend event (19-20-21th november) I probably gonna sell and buy few DO cards including Bronze Gate. It might turn out a better replacement for Minotaurs and I already can see it would fit a mana curve even better!
Don't forget to check the star store too. Sometimes you'll find valuable core cards there as well.
