The issue is that the land, Mox, Chalice opener is not very likely to happen unless you have the luck of the gods, and against tempo decks it's pretty risky unless you're on the play. I would be very leery of raising my curve against Canadian Thresh decks; you are pretty soft to tempo decks, especially if they get a fast start, and the upside of Chalice locking them out of their dig spells and flying Nacatls is massively offset by the turn you lose if you try to resolve one and they counter it, or you wait to resolve one to play around Daze and they counter it anyway with Spell Snare or something.
Outside of tempo decks, I don't really see why you would need Chalice.
