Why would you want "Tool Scrapper" reprinted? Startling Mega Phone is VASTLY superior. Unless you want to try and run the Team Flare Gear stuff maybe but IDK are any of those REALLY all that good/viable.
When in doubt, research! Or at least ask your questions so that it is apparent "Yeah, I don't know this." I personally can't speak to the viability of Pokémon Tool F cards at this moment and (more importantly) when this set releases, but yes there is a niche for Tool Scrapper. Pokémon Tools are good enough that few decks run none and both for getting rid of an opponent's Pokémon Tool F and selectively discarding an opponent's Pokémon Tools, it has legitimate merit. As I think you were stating, it allows you to discard an opponent's Pokémon Tools without discarding your own Pokémon Tool F but it also avoids discarding an already-used Spirit Link or similar "More useful to me since it blocks their Tool slot" card currently attached. Tool Scapper also can discard Tools from your own Pokémon in those situations: so countering Pokémon Tool F and allowing you to go "...discard Spirit Link, attach Muscle Band".
Note that I do not want a Tool Scrapper reprint - I think there are too many overly potent Pokémon Tool counters right now.
