I reread the rules and don't see anything that excludes this army, can you point me to it ?Not sure about the first choice, TC, as it states Rise of Persia and Immortal Fire, with FOG DLC only
Personally I preferred what Pete did with the DL and had lists of armies for each period, so each army fell into only one period and thus the choice was more restricted. The TDC has allowed more flexibility with quite a few 'overlap' armies.
