My mod has two Heroes (Sitacles and Teres 1) and three civ bonuses (+5% population bonus, +1 speed but -1 hack and pierce armor, and a champion peltast).
I think I planned for the team bonus to be a special Thracian Peltast Merc for allies.
The champion units were in my mod were the Thracian Black Cloak, a champion Peltast, and a Calvary Skrimisker.
