Errata, if any is needed... Illusions of Grandeur comes into play, it's owner gains 20 life, when it leaves, it's owner loses 20 life. An imperfect fix, I know. But... No bannings required, Donate decks still work, but Illusions/Donate is a thing of the past. Delusions of Mediocrity rises to take its place, but at least they gotta do it twice. If there's a banning, Illusions is the one to go, unless Necro really is the problem, then it's Necro. but the deck work without Necro, just not as fast.
