I've been thinking about Time Walk and it seems like the best case is pass turn with some hollow ones and vengevines out but in most cases its an explore plus untap. Now that might be good enough but most combo turns I never have extra mana and taking up 2 mana in early game turns is hard to do and still be productive in comboing.
Also is Ancient grudge worth looking into instead of Ingot Chewer in the main as it can be tossed to Bazaar and is better vs shops since Thorn and Chalice have been restricted (IMO).
I for one am foregoing White entirely as I don't own containment Priests and running a second Trop helps cast leovold easier which is a super potent SB option vs Outcome decks. I have had people scoop to t2 leovold when there hand is a turbo PO only hand.
edit: Although I don't know how to beat oath now; Golgari Charm maybe and run a second bayou instead of trop? -1/-1 is super good vs monk young peezy tokens and regenerate it pretty much useless with toxic deluge being the go to sweeper. Or just run Abrupt decays in the side?
