I think it's really really good, even with Enhanced hammer back.
-Being a supporter actually has it's advantages now. It can be brought back with VS Seeker and can be played when Seismatoad EX is causing Mayhem (that's the main reason I think this is good). Just hope Stoutland or Exeggutor doesn't become a thing.
-It's versatile. It's like having two cards in one. It's either half a tool scrapper or an enhanced hammer. This means that playing a copy in your deck is like having two cards, each covering a different situation (both of which you're bound to run into)
-You can use it on your own Pokemon. So if one of those Team Flare Hyper Gear cards is causing trouble, you can get rid of it, allowing you to attach advantageous tools like Muscle Band. You can even use it on your own energy, which can actually be useful against the likes of Aegislash EX, which is immune to Pokemon attacks if they have special energy attached.
It just seems like a card that was made for the format, not just Seismatoad EX, but Garbodor, the hyper gear tools, and even something like Aegislash EX.
