Only in very specific decks good. Thrown in a random deck it's not worth the effort. If your deck would have 50% creatures, then every second time you activate this card you'd get a creature into play. Which means if all those 50% of creatures do cost 8 mana, you are still not even, because you paid 4 mana in addition to play this card.
If you have a way to stack creatures on top of your library, then sure it's fine. Else: no way.

Use Mirri's Guile and put a creature there. Now you have cheap Tidespout, DSC, Inkwell, everything.

Best in blue/green, which has plenty of cards that reveal the top card of your library, many of them creatures, and two, Mirri's Guile and Field of Dreams, that cost only one mana each. Add in some land-searchers (they trigger shuffles) and card drawing, and you've got the core of a great deck.
No need to branch into blue. Stay green where the big creatures of doom are!

I had never seen Oracle of Mul Daya before. That card is a definite addition to my existing Call deck. I've been playing Call since it's first printing in casual play, but throw in a few Oracles, and I won't be wasting my resources.
