I guess, you don't really need
Echoing Courage in this deck, cause essences are quite strong enough and +2 to each won't make much difference to spend a card on it. Also consider
Life's Legacy as a nice way to draw cards.
By the way,
Fierce empath is the only card that gets your deck out of modern type, downward to legacy. You might want to replace it with Ancient Command, which will also grant more protection from noncreature permanents.
