If you can do that many wishes, just get a removal for the opposing karn and slam the lattice. (I mean, why else didn't you slam the lattice already?)

I'm more talking about if you were against something like Dredge, where them casting spells is not really important but their graveyard contents are.

Also, it could be the case that they just answered your Lattice. My comment was not intended to be an idea in lieu of playing Lattice, just pointing out a possible interaction that plausibly be relevant in some cases, and/or potential future design space cases.
