Nice effect, but it's way too expensive for just that. If it returned to your hand, then it would be usable, but as it is, it's near-useless.

actually, it's pretty good. What if you know your opponent plays a Grindstone + Painter's Servant deck? Then he can't really beat you because it will eternally keep shuffling back into your deck.

Alicanto, it needs to be in play/on the battlefield first to be shuffled into your library.

Pretty much all the white dragons suck. If you only play white and insist on having a dragon in your deck, Eternal Dragon is the most playable of the bunch.
