Actually, I see Sundials as somewhat useful here, for three reasons:
1) They are inexpensive and can lead to a faster deck, a la Precognition - same amount of draw acceleration.
2) If you don't get creatures out immediately but your opponent does, they can provide better survivability.
3) Even if you already have Golems out, they are growing while you wait. The delay isn't hurting you as much as your opponent - unless he's got growth creatures too.
