If your gonna get rid of the Spiritdancer you could use Silhana Ledgewalker, but you'll definitely need some beefier auras to punch with. Something like Spirit Mantle will at least let you clear unblocked damage.

out with Kor Spiritdancer And in with1+ Witchstalker1+ Troll Ascetic2+ Sage's Reverie For card draw ?

HiddenStrings both of those are really bad because in modern you need to drop one of these creatures on turn 1 the only thing that could maybe make this better depending on your meta is one of Dryad Arbor over eidolon because while I respect what eidolon could do I still think its bad in this deck I also believe both of this spaces could be better used for lands I only say dryad arbor because if someone minuses Lilliana then you fetch it in response so you can sac that instead

Witchstalker and Troll Ascetic will slow down the deck. Witchstalker is best suited for the sideboard. Sage's Reverie could be a decent late gamer.

Jake1515, while there's definitely no literal replacement for Daybreak Coronet, we can definitely try to fill the void as best we can.

cjk191997, I ditched the Dryad primarily because I'm ditching fetches. This is also a casual budget deck.

Rabid_Rabbit, I had thought of Silhana Ledgewalker, which due to the low cmc and reach may end up making it in here.

HipsterKitty, Sage's Reverie is an amazing card, but the cmc would only make me want to play it as a one-of.
