Why would you need a Tooldrop counter of all things if you are playing Crobat? Exp. Share doesn't activate if the Trubbish is knockout by poison damage. If the raw speed of the deck is the problem, I'd hate to see what your darkrai match up is like... Seriously though, I wouldn't over tech, that is where you are going to hurt yourself. Adding things like Garbodor and Chatot are going to be completely dead cards in every other match up. The game against Tool Drop can be won if you outplay your opponent, simple as that. If you are really tech eager, add 2 Tool Scrapper, and a Meloetta. Those cards are going to be useful in almost every game that you play, and they completely wreck tool drop, especially if you're playing Super Rod to recover the Meloetta. If you are feeling adventurous you can tech Crushing Hammer. Sets the deck an entire turn back, removes grass energy in Virizion Variants, but the coin flip is pesky.
