Shamans aren't getting any help so far. They were already an RNG mess because of the focus on evolution. Now they are doing a random spell theme. Problem is shamans have far to many subpar spells on the basic and classic sets. Back into your hole shaman, Blizzard still doesn't forgive you for your aggro hayday.
1/1 is much better than 0/1 for 1. It doesn't trade with anything and the spells it gives are generally much weaker than those of the Mage. There is no point in comparing it to Babbling Book. I don't think it will see any play.
Shaman has some good random spells to get... however in turn it has some horrid cards that can fill your hand and be largely unusable (Totemic Might). Sure it looked neat in the demo coupled with Hagatha... I don't see this being worthy of running in a standard deck though.
With the Mages Babbling Book, I think they have a better pool of cards that can justify taking up 1-2 slots in a deck for the RNG fiesta that they are.
