5 agents for all maps

If you could only use 5 different agents across all maps(not pearl) what would the best comp be?

I was thinking:
Chamber
Omen
Kayo
Raze
Sage

you need viper on breeze, icebox and sometimes on bind too. so i would probably switch out sage for viper as we've seen some sage-less comp succeed in icebox.

have fun running this on breeze and fracture

-Sage +Viper

maybe fade instead of kayo

Astra(main smoker)
Viper(important for maps like icebox breeze and good on maps like bind split fracture)
Neon/Raze(both good duelist for entries)
Chamber(yes)
Sova/Kay/O(initiator both have their own reasons why they're good)

Jett/Raze
Chamber
Viper
KAY/O
Sova

Interesting question. Riot did a good job of balancing and spreading out agents to have their own place in a map pool (except Chamber, that man is too op)... Here is my take

Anchor / Flank / 1st contact - Chamber
Duelist / Entry / 1st contact - Raze
Initiator / Info Gatherer / Secondary Entry - Skye
Anchor / Lurk - Viper
Main Smoker - Astra

Chamber is obviously the most efficient and easiest agent to find value with currently.

Raze gets the job done on all maps except Breeze, where different utility combos must be utilized.
Viper is an S tier agent and untouchable on Breeze and Icebox (also Bind, but you may win it without her), but definitely cannot be a primary smoker on maps where she is not as efficient. On maps like Haven and Ascent, she would serve as a site anchor, while the primary smoker would be Astra.

Even though overall Astra is not an S-tier pick, in this case, she would pair better with Raze and Viper (use Fnatic Bind as an example). Her kit would focus more on pulling and stunning on Breeze, Icebox, and Bind, rather than her being the main smoker.

The initiator role is a coin toss really... With the rest of the team comp any agent would make sense and would be absolutely unviable on some maps. KAY/O may just be the most efficient out of the bunch, but I could see Skye prevailing as she is a jack of all trades type of agent, but she would be utilized a little differently than what's usually the case (more info gathering and less of reactive utility usage )

Raze
Chamber
Breach
Fade
Viper
