There's so many ways to go with this since it's 4 colors. Since we mostly only want chance in the late game on 5 lands or more, I decided to make the deck base simic and added deputy to try it and knight of autumn because I like making choices.
There's about a million ways to build this combo though. Eg. cutting jadelight and wildgrowth walker, then cutting green sources for white, can make casting spells slightly easier.
Adding value 4 and 5 drops or memorials can give the deck more late game and a better plan B than anticipate and 2/3 drop tribal. Since chance for glory is such an all in card I decided "screw plan B".
Edit: I've since cut anticipate even though it works well with teferi plus.
You can add hydroid krasis or preconceived perceptions for late game. Or just add value walkers like vivien and domri. Replicate doesn't work well with krasis though and provides vivien reid with a target. Karn + treasure map can sorta work. Maybe expansion / explosion or chemister's insight.
You can add black for tutors. Maybe in addition to cutting green or blue entirely or playing some more fixing.
You can go base boros for an aggressive deck that can use chance for glory as a plan B to just kill the opponent. Replicate a hasty creature if you don't draw chance or counter something with repudiate.
You can go hard on the simic and play frilled mystic/quench/spell pierce to counter control decks that try to counter repudiate.
