The owl first and foremost is a grass-type which means it has shit stab, its movepool isn't spectacular, nor does it have the speed or offensive stats to take advantage of what it does get. Spirit Shackle as a trap is extremely ineffective and traps don't pass with baton pass. It's completely shit in singles, due to the baton pass ban in UU, which makes its only niche as a spinblocker/defogger, which is retarded when you consider that defog gets rid of traps on your opponent's side as well.
tl;dr: It's a archetypical grass-starter. It wishes it can be Venusaur, but it will never be.
