Awesome card! this will do wonders for the Exalted decks, I can imagine playing this on turn 2 with the help of Noble Hierarch and using Cascade to put a Sigiled Paladin into play for free, then attack in turn 3 with at least a 5/5 First Strike (or even more) or in times of need having a Path to Exile coming from the bottom of the deck to deal with an annoying enemy creature and have the Exalted boost so your creatures can deal damage without worries that same turn!!
But anyone can picture that, other thing I like is the art on this card, is beautiful and its so nice to see Elspeth, she is my favorite Planeswalker!
