I beat Yomi early era with the pale ones, however, the pale ones cheap grunt troops suck against a decent unit, I beat him with magna units and Loads and Loads of Bemeaths at least 30-60 in each of my armies. Beameths don't route and trample even demon into powder. So I would suggest, that when you fight him, I would take a Fire or Death Race and give your Pretender high death and Fire magic. Be sure to give pretender high enough to start getting Bemeaths as soon as you research it. in the mean time, enpower some of your mages so they in turn, are level enough to also throw bemeths. If you have 5-6 that can trhow it and have enough gems Your on your way. Put the bemeaths all along the front with your other troops on the far flanks in narrow lines.
good luck, This is just what I've used to beat another human player who also took Yomi, have fun, good luck
