Not much of an improvement over Base set pinsir, IMO.
Delta search is too narrow to make it hugely useful, guillotine is fairly standardly boring.
Armour, however, does make sense on a 60 hp only basic, punishing your opponents for their card drawing trainers and over-use of situation-only cards. For example, with this out and a full hand, they are gonna drop spare basics to the bench, that could cost them prizes with a bit of gust effect.
Armor, I think, is not enough to turn this very average pinsir into anything top-tier.
