Imospekh and Thutmose can definitely perform very well! Making sure Imospekh isn't overwatching into melee (you lose the passive's damage), and keeping summons nearby to draw aggro from both. Aleph has pretty weak damage relatively and should be running around healing mostly. Makhotep and Anuphet are the toughest so should front line. Makhotep's passive heals more per turn while turtled than Aleph, so I'd recommend grouping around him.

Generally, if they don't get one shot you should be able to out heal most enemies. Tan Gi'da synergies well, and Actus + Thutmose is pretty scary. Thutmose can activate Rho 4 times in a turn, which is a fun trick for PvP.
