The caveat is that Fire lacks Burst gauge buffs, so ensuring that the Soul gets the Burst buff requires sacrificing debuff potential from the Soul.
Joan + Black Propaganda would be highly effective for Fire teams post-Mars, as it covers Fire's main weakness: powerful Overdrives and lack of endurance. Pre-Mars you wouldn't have sufficient DEF down, nor would you be able to land your debuffs reliably. As long as Sphinx is ready to ensure Mars's debuff lands, Fire is freed from the need to run Mordred all the time.
So post-Mars, Fire has the choice between a Burst build and a Versatile build. I would favor the Versatile build for solo content, and the Burst build for group content.
