I believe its "add_money x". Personally I think that Epeiros is the one with the best chances thanks to those elephants. I can usually conquer everything but the Peloponses with those guys, and after that it is a question of simply keeping a half-decent army, just in case, to guard your cities while the Koinon Hellenon and the Makedonians slug it out on the Peloponese. Its often possible to take Chalkis and Mytelene (the settlement next to Ionia on the Island) also if you have a couple of Pezhetairoi left over. Though if you do this its very possible to go as much as 50k into debt, and it is very hard to keep Tarentum (though if you do you have a great base for launching strikes into Roman Territory (DIEEEE ROMANS!!)).
My only beef with the Epeirotes is that their "elites" do not match up to the Makedonian/Seleukid ones (their best is, I believe, Illyrioi Thorakitai, which is only 12, 24. Compare that to Pheraspidai, Hypaspitai, or Thorakitai Argyraspidai)). Overall though, they have an excellent list of units.
