Starting with all your positionals give you a solid line up to start and will help you to skill up quickly your key players, 2 re-rolls could be little risky and you will need to be careful with Frenzy although you have Juggernaut that will help you to deal with it. Also, you have 2 Block + Jugger blitzers and 2 ST4 with Jugger and PRO that should be able to manage re-rolls fairly easy. In addition you have and APO that could help to prevent injuries in your key players at the beginning. First purchase should be a 3rd RR and then increase your bench.

A small variation of the previous roster, you switch APO for 1 lino bench. First buy should be an APO and then 3 RR.

This roster sacrifices the 2nd Wolf Kin for the 3rd re-roll. This is a safer way to start for beginners players as you have 1 re-roll more and less Frenzy on the pitch to manage. You have 40k on treasury so you will get the APO after your first game, then increase your bench with a Wolf Kin (if you feel confidence to manage Frenzy) or with linos.
