I think going for a large team could be essential with all that AV 7.
All Skaven + Troll, 8 x Goblin , Apo , 2rr, 1x CL . 15 players and Apo,

First or second skill will be Leader . The other ones:
Wrestle / Lino
Claw / Troll
Horns / Blitzer
Guard / Blitzer
6th skill not sure . Two Heads Goblin ? Block Thrower ? Strip Ball / Wrestle / Guard Goblin ? I am not sure if I really will take the double , Claw on Troll is more important IMO and don't want to take a lot of skills on Goblins.
