I bought the storm claw box set to add to my wolves and now starting at small ork army to be used as allies. In the book the Formation Grukks Rippin Krew can arrive buy deep strike on the first turn and no rolls needed. my question is i want to use the all an allies unit with my eldar, Can they be my allies legally? Do still need a Allied HQ, and two troop choices to use them? I might be over thinking this but i just think dropping that whole unit in someones face on the first turn is nasty, almost to good to be true lol.
