Yes, that is more or less the team I used. Which is Aegon and supporting champions. I had some different supporting champions but you've got the two main ones (Heimdall and Proxima) as well as a champion that's immune to reverse controls (I used Wiccan). The last spot is kinda optional - I went for Nick Fury in order to give all of my champions a 20% attack boost - but Chavez will do fine.

Rank 2 7* Chavez
Proxy and Heimdall for synergy
Rank 4 6* Juggs for reverse control at gm
Godspeed etc.
If you have a 7* shuri tho, take her instead of proxima. If you don't have one, it's fine aegon can still do those fights.
