Not very Ancient Egyptian though!
OMG!!!

RANTALARM
Tomb kings are not ancient egyptian. the basis for tomb kings came from both ancient egypt and Mesopotamia.
Furthermore, heavy cav are fine. yes a little low on the armor save, but given what they are based from, the armor level is appropriate.
Now, don't get me wrong, even though the TK army (which I now have 3k of -my first three thousand point army) is based off of those two nations, they have thier own distinct feel. To stop this post going on too long, I will refrain from posting my essay on the subject.
Also, please do not call tomb kings "khemri". Khemri is one city out of nine. It is a misnomer I hate teaching people about.
END RANT ALARM...........for now.
