Yeah, I mean I see what you're saying. Part of the key was dropping the power level so that the baseline power requirements were lower. It's also structured much more like a retail draft set than a traditional cube.
I actually think Lucas has some good points here. But what they fail to provide to me are any compelling reasons to run the cards. "It's not that bad" isn't the form of defense I'm looking for.
I think generally draft environments want cards with a higher base power level. Relying entirely on synergy is basically a death sentence for a cube card. I'm sure you can find exceptions in the posts below. :p
