ROLL THE BONEZ
I think Knucklebones can be really good if you build a Shimmerpack-esque shell around it. I wasn't doing so good with Harsh Rule/Knucklebones decks, so decided to try Sandstorm Titan. The idea is to not die and clog the board, letting Bones take you home. Obelisk makes your Bones dorks much more impressive. It feels like Siraf, where the random units are much more imposing with a stat boost.
Often you don't just wanna jam Bones on turn 7. Having more power means more tempo to spew out your dorky cards. If you have an Obelisk out you'll obviously want to wait till 8 power, that's where I'm comfortable Boning myself.
