Go with gken's roster. You want 4 mummies right away. Definitely 2 blitzras, because a weakness of a rookie khemri team is the complete lack of block. Any team that has a lot of block can even things up a bit despite your 4 bruising mummmies.
On offense, it's pretty simple. Cage it up with the 4 mummies and use the skellies as fodder to clear a way. You'll move slowly, but that's what you want. Bleed the clock and the other team. A cage is pretty intimidating when all corners are manned by a St 5 brute. Incidentily, you'll want block on those big boys, b/c you'll take a lot of suicide attacks from opposing players who have block, and whose hope on a 2 die is double block, or some sort of result besides skull and pow/skull.
Defensively, it's easy to load up the los with 3 or 4 mummies, but then you're making it easy for the other side to plug its bums on the line to keep 'em occupied. I like to keep at least 2 in the second line of defense, to be used as fearsome blitzers. Sometimes 3 or all 4, depending on the team I'm playing.
Don't doge. Ever. Unless you manage to get the skill somehow, or you have no choice.
Sure Hands, a must.
Watch out for this tactic by the opponent. Often enough, they'll ignore your mummies and go after the skellies, and position players, in the hopes of leaving you nothing but AG1 fellas on offense.
Set up, I've found, is critical. Stick to your set up plan, and refuse the urge to adjust to his set up. He may have a good looking snack on the los, but don't screw up a cage of mummies to do a little pounding. It may cost you a shot to tie or win, when you have to have 1 mummy hand off to another who then has to take it through a tz (long story, but a lesson learned well.).
Have fun, Khemri are a blast to play.
