I have a khemri team "Low Fat & No Sugar" on Naggaroth. 2-1-0 with them and they are kinda neat - but also definitely a HC team. Tomb guardians can die any second thanks to 'decay' and although not too expensive (100k), they are pain in the ass to lvl up (no mighty blow).
Blitz-ra are the worst blitzers in the game and still cost 90k. You can have two of them and they are the only players with block.
As the whole team team has AG2, good luck picking up any ball that is marked by opponent. Throw-ra have ag2 + surehands so thats 75% chance to pick up the ball, when someone is not marking it. If the ball is in opponents cage, well thats it then.
Also the team is slooooooooooooooooooow. throw-ra and blitz-ra have MV6 (that is 4 positionals), skellies mv5 and TG mv4.
Ive succeeded at dodging few times, but that is 50%...so its a way to waste all the rerolls if you feel like you have too many.
All-in-all, i feel the Khemri are most grindy team in whole game, yet are definitely NOT the best team in game to do that strategy. Dwarves, orcs, chaos dwarves and chaos are way more reliable at that.
I must admit ive considered if i should go for khemri on third season (if i am bored with the vamps, no idea yet), but well, the grindy no-dodge, no-pass gamestyle can get "abit" tedious eventually i guess... Then again if i happen to freeze the vamps, i might just as well go with the High elves. or something else ;)
-> but if you want to learn how to grind, Khemri are you team - as thats the only way they can play :)

For a bit more flexibility and reliability id recommend you try Orcs (0 teams so far) or the vanilla Undead (0 teams so far).
They both have lots of str, better mobility, more skills and more AV than the khemri. Both can do slow grind or even a bit speedier game (undead with ghouls).
