Yup it's been really fun. Hard to climb for sure as you can't really tailor to a meta since there seemingly is none. I bounce between 9 and 13, depending on how crazy of a deck I am testing out. But the truth is unless you're aiming for legendary, there's really no reason to worry about it.
I have a cool mage deck I put together that is pretty fun and somewhat consistent. Unstable Portal is so fun
Here's a game where it allowed me to beat a handlock I probably had no chance to beat otherwise
I also tried to put together a warlock mech/demon deck. It didn't do that well but a lot of it was due to shit draws. I have a soulfire and a hellfire, and for 3 games straight I never drew either of them in my first 20 cards. So I added a second hellfire and sure enough the next game all 3 were in my opening hand, along with a 6 drop, after a full mulligan.
