IMO, one of the biggest advantages to Chrome Mox is the ability to survive T1 Blood Moons that much more often have have more "virtual 1-drops" to start the game strong against Chalice.

I think you should be running some regular Thalia in here; T1 Thalias are *insanely* strong against blue/combo; including all of the moon/chalice/etc decks. One of the best lines you could do with DRS was T1 DRS T2 Thalia + Wasteland. Those lines still exist with Moxen and (imo) should be taken advantage of.
