Hey, that's right! I just tried it out: by assembling Adhesive I was able to drag the adhesive onto the "cursed block" (which looks like a block with no number next to it) and the cursed block disappeared.

Also, I didn't notice this before but of course you can "throw away" any stack with a number next to it, so if you do end up with a stack of thousands or millions, you can get rid of that easily without needing to assemble something.
