The Tentacled One
I just saw a picture of the "Summer Magic" printing of Demonic Tutor. Hadn't remembered this, but the pentagram on the demon's forehead was removed. They missed the one on its chest, so apparently they either just gave up and omitted the card from Fourth Edition or the card was so powerful that they decided it didn't belong in the core set anyway. Maybe a bit of both. I dunno.I know the art on Unholy Strength was edited, but were those other cards actually removed because of their art? Fourth Edition had a lot of changes from Third/Revised, and those cards were only a few of them.
