There is Urza as just a Creature; Blind Seer. He is disguised and is also sort of a terrible card with weird flavor.
That said, this card was better in the environment it was in as opposed to the one we have now where true draw-go is a distant memory. Being uncounterable no longer matters so much early and late you have the variable Banefire which sees no serious play. All that said, at least it is a main deckable sideboard card.
