Well, only antlion larva make sand pits, so that leaves Arena Trap out
I dunno about Sheer Force, and it seems to me they wanted to emphasize Levitate a lot more due to how adult antlions can fly. After all, this WAS the generation abilities were introduced.
Flygon's stats don't exactly help it a lot, as most Pokemon that have relatively evenly distributed stats try to do one thing but fail to do another, and end up not being that good at the stuff they are good at because of all the other stat numbers going into something else. There's also being outclassed to keep in mind.
Overall, Vibrava and Flygon just kinda exist, and Flygon is still in a strange position, despite having FINALLY gained Dragon Dance. Although it's much better having Dragon Dance than not having it.
