Most of them are very strategy specific.
Green has Glimpse of Nature/regal force of elfball stuff. I don't think it has much else that has not been mentioned that is worth playing. Maybe some cantrips like Oath of Nissa in a very specific list?
Red has Squee, Goblin Nabob and the looting cards/bazaar. Goblins actually have a wealth of options, and red does have a new wheel effect in Wheel of Misfortune. Light up the stage is ok in burn decks outside of vintage but I feel like it would fall flat in vintage. Valakut Exploration is not something I have seen tried out to much yet but seems like it could be a very strong personal horn of greed, and Jeska's Will got overlooked because it says commander on it but it is actually just a strictly superior Act on Impulse.
White I think you'll need to look at land tax or artifacts. There is stuff like Mentor of the meek and enchantresses of various sorts but those have long been removed from the format.
