I have used the two teams from the quick start rules + Hades with Cerberus and Infernal Warriors.
Worked well for us at least.
Hades + Cerberus + Infernal Warriors
Zeus + Hydra + Spartans
Ares + Achilles + Hoplites
I also opted for a setup very similarly to this, although I substituted Cerberus for the Minotaur.
