I also try to minimize my interventions in the game by using spies and assassins. As the Ptolemies conquered all of Selucid holdings, my agents caused revolts in Halicarnassus, Ipsus , Byzantium ans Anykira. Now its Pergamon and Mazaka the targets. The problem is that the Ptolemies take these lost cities quite easily, but in North Africa they are losing land to the kath-Hadast, their armies are over stretched.

Cheers.
