Quint doesn't really compete because it takes another card space. Furthermore, Quint removes all possibility of Rewinding anything, removing the main use this provides. 3 cost for 4 attack is fine unupped due to the heavy drawback. Upped, it could easily get 5-6 attack. It's not really necessary though, because this strengthens Air/Death or Air/Aether stalls, and you need only pack one. This is also a big boon to all deckout decks, because it's much easier than packing Eternity+a target. I like.
