PTQ Sealed Card Pool

[fractal9091]

Well, it's another Magic-related post (as opposed to a paper-related post; sorry that's all I seem to write about these days).

Despite the benefit of hindsight and additional experience, I'm still not sure how to build the sealed pool I opened at the PTQ. It's interesting, because the creature base in all five colors is quite strong. Anyway, I'd appreciate feedback, from those of you who play Magic.
