Ooh! I love this artwork! This looks like a new artist too, I don't recognize the name.
Without some good non-water non-fighting fossils, this card is kinda useless though. Cradily is the only one that doesnt have Maxie, Archie, or Fossil Researcher to help get it in play, and the Stage 2's in a Cradily deck would probably get in the way of Archie-ing out the Omastar in the first place. (Not to mention they probably aren't taking Expanded into consideration. ) I doubt they'd print something like this without somethin else to go with it in the set though.
I hope there's a fighting type Kabutops! Fighting would be nice flavor too, as it's the offensive one of the pair and it'd be able to use Strong Energy, etc. (As opposed to water's defensive theme) Maybe it'd be a strong attacker where using Omastar to stream Kabuto would be more reliable than Dome Fossil?
