Is this allowed?
My opponent had a Heimerdinger and Glowstone, and said he could "give me" the heimerdinger?
He said because Heimerdinger was empowered by some other card he was allowed to do this???
I argued that such a dumb interaction should never exist in this game, but he said that I was wrong and that it was a legal play.
Anyways, then I just called him a slur and left.
