I personally don't like three element decks, or big decks with more than 30-35 cards so my first two suggestions are to cut some cards making your deck smaller and change it to a duo deck instead of a trio deck.
I agree that you should drop the Life cards cause they aren't helping you that much. Time/Aether is a decent combo, there is some synergy between fate eggs and parallel universe, you can hope you pop something big and mean and then copy it. Eternity is tough cause it costs so much time to use, if you want to keep it in maybe you should try switching to a mark of Time.
