Do you think GF will introduce something that becomes a hard counter to these moves? We got Black Sludge to counter the switching moves, but that's only usable by poison types and you get stuck with an undesirable item.

I was thinking of an item that would not only hurt the enemy but also stop the damage and secondary effects of said moves, so trick/switcheero users would get to keep their choice scarf/etc. and your mon won't get crippled. It might work wonders on Unburden users, specially the ones that resist Knock Off.
