on my next tourney i want to try my khemri team (played enough Skaven and CDs

The rules are the following:
1.100.000gp
3 normal skills
no Star Players
LRB 3.0
3 games, after every game another normal skill (not 2 skills on 1 player)
possibly final (dungeon bowl)
I thought i take the following team:
4 mummies
2 blitz-ras
2 pick-up -ras
5 skellis
3 rrs
1 ff
3 skills: 2 * block on mummies, 1 dirty player on skellie.
What do you think of this team? Are 12 players important or better - pickupRa and + reroll?
Is it playable on a tourney?
Are the 3 skills wise?
What skills to take after the 3 matches? I thougt of maybe block on the other 2 mummies, guard or tackle on blitz-ras, kick on skellie, i can´t decide...
Thanks for your help
Tobias
