Cool, seems funny and well designed, great for control and value decks. 4/5

If the battlecry can target also himself is 5/5 easily, anyone knows?

This card fits perfectly in the big spell mage. Its a super solid card, ARCANE, and for me is even better than the 10 mana spell by far, the untargettable keyword is nuts, do you remeber the exp of the dragons how broken they were? 4.5 stars easily, not 5 because 5 stars is for meta-defining cards.
