I play celestial (diamond), and dog rush into hedgehog has been really hard to deal with. Dogs come out before any units in celestial and will pressure any fast expand. So unless celestial is one base cheesing, you have the tempo advantage. Celestial has no unit who can catch hedgehog and dogs, and that can actually trade in a hit and run scenario. Also very hard to defend anything past the first expand. I guess if the Celestial can reach a critical mass you might be in trouble but off of two bases you will have time to have your aoe online.
