rules
As to models, really just make a team out of WFB models, or frankly find out what you want to play and a guarantee one of us has a team you can borrow.
If you are a new player I suggest humans or orcs. If you want to get adventurous, perhaps amazons or undead as they are fairly forgiving. just be very careful some players want to start with their favorite race, which can sound fun, but some teams are a challenge to play, not due to un-balance but because of the very strategic thinking you have to have to play them. example dwarfs, tough as nails, but their speed means you have to really plan our your moves and think many turns ahead. Another example on the opposite side is Wood Elfs, fast and easy to do what you want, but more often that not you will be playing with a player disadvantage as your players get hurt. Being able to score with just 3-5 elfs is doable, but you have to be good to make it happen consistently, and honestly in a game where you guys die....regularly, playing a team that is known for the way to beat them is to "beat them down", can be frustrating.
