Depends if they'll get a TOTY card, they shouldn't but who knows with the voting. If not, the best chance you have will be when all of the TOTY cards are in packs and there are 100/125k promo packs running. People will keep undercutting until the supply dries up.
There should be a bounce back after that and then a drop off again when prime icon moments cards start landing.
