I can see where
starfield of Nyx may seem out of place here, but given its ability to pull enchantments out of the graveyard, and turn enchantments into creatures, it would be a mistake to leave it out imho. However, I have noticed playing this deck a bit, that it is missing low end drops (1st-3rd turn) which can be critical if you are playing against a control or aggro player, so the sideboard has a few 1-2 drop creatures to speed things up if needed.
