I counter your magic by transforming myself into a Lojbanic Elemental. I proceed to hurl /jbo/mbs at everyone on the hill, stunning them as they attempt to figure out a logical language. While they do that, I plant the Lojbanic flag on the hill and enchant the flag with Impossible Conlangs, forcing anyone attempting to modify any aspect of it to learn an impossibly complex constructed language.

The hill now belongs to the Lojbanic Empire.
