I agree with the idea here, because the card can still be powerful, it just isn't the basis of decks. For example, doubling this card with quintessence and any creature will give you that skill free for every turn. You can still have anubis give infinite quintessences if you just have 1 to begin with. Same thing for flying weapons, otyugh, bla bla. Having a flying quintessenced eternity with this will keep you going forever, negating a few shields. I like the nerf.
