Finding Baby Moses doesn't do anything Moses doesn't already do, except add numbers (aside from the CBN, which is okay, but not good enough to make it deckable). High numbers can be solid, but not enough to merit an add in already cramped spread OT offenses.
The Vineyard is slightly overpowered as an Isaiah enhancement. Hidden Treasures and Isaiah means it can be infinitely recurred to clear out a deck very quickly. Search is more vulnerable than drawing, but it's also more efficient, and in the end, I like it better if it's not something that can be recurred so easily by such a good hero.
