Dude, Thomas Blake works as a thief primarily. Sure, he's a batman-knockoff, but Batman has DEDICATED his life to doing what he does, and so has Owlman with CONSIDERABLY less restraint than Bruce. 

Thomas is not his equal, but he can come close.

in his bio I stated that he began training since he was young and he also did mercenary work. At the very least he can hold his own against Batman and he stale mated bronze tiger in the comics who if I'm not mistaken is one of the best martial artist in the dc universe.
