I'm a bit hestitant to admit it, but I'm a filthy netdecker (and I'm pretty sure I'm not the only one). Even if I'm repeating myself, outof.cards is the most awesome Hearthstone page on the web for me. Still, there are two things that are closely related to each other which I have to look for on other pages. So here are my suggestions how you could at least partially avoid that if you wanted to:
1) Top decks
Not sure how the algorythms work, but right now the "hot" and the "top" decks are showing almost the same results. You have that cooperation with HSReplay running, so why not use it some more? I suggest keeping the "hot" section as it is (I guess it's based on views, comments and upvotes?) and displaying the lists with the highest win rates from HSReplay in "top", updated daily at midnight or some such. Sometimes people are just looking for the best decks to grind the ladder with and right now, it's quite difficult to find them if there doesn't happen to be a post like this on the frontpage. It goes without saying that keeping the filters as they are would be vital if that is possible.
2) Meta Reports
This might be a little insolent, but I'd really appreciate it if there was a section where you point us to meta reports. Everybody has their favorites but I think we can agree about the top 3 or something. You could either post a short news article whenever a new one comes out or silently update a site where they are all displayed with a link to their respective external site. I know this would be pretty much advertizing third party content but since OOC understandably can't provide such reports themselves, why not make things for users a bit easier? While we're at it, a collection of podcasts would be pretty awesome, too.
I hope you don't get these ideas the wrong way. It's just that OOC is my platform of choice for everything social about Hearthstone right now, but if I want to be competitive, I have to look elsewhere most of the time. Maybe you are fine with that, but if you want to cater to a bigger audience, the two points above might be places to start.
