Against BUG, UWB, UBR decks this might win me the game on t1 if they don't have FoW (very tough to cast Abrupt Decay or Council's Judgment on Blood Moon with 0 non-mountain fetches). Chalice 0 on t1 is to prevent Mox Diamond, Chrome Mox, Lotus Petal, LED to fix their mana.

A weakness of this approach I can think of is that the opponent can cast a T1 Faithless Looting off their mountain. If the opponent is Dredge, this can be bad, if reanimator, they are struggling to get B mana. Belcher and Burn are also undisturbed by the moon, but I am hoping the t2 Chalice 1 is enough to disturb them.

Chances are, the opponent does not have a basic swamp in hand for DRS, basic forest for Noble Hierarch or basic island for cantrips/counters/active daze, making them completely miss their t1 play.
100% this. You want to stop the first basic before anything else.
