This type of post has always been to show the most popular decks on the site for the entire week with no filter. With that said, we could definitely do a better job at promoting deck guides from all types of community members. I used to do a ton of deck spotlights but it fell out of favor over the past year for various reasons. It especially gets hard when Hearthstone hits spots where there isn't much innovation and all you end up seeing is complaints like "not this boring shit again".
If anyone ever comes across an awesome guide on the site they think deserves some front page love, my inbox here is always open and I'd love to see your message in it.
