Is he trying to build a competitive tournament deck? Werewolves won't do that well.
However, you can make a very fun casual deck:
4x Reckless Waif
4x Mayor of Avabruck
4x Gatstaf Shepherd
2x Daybreak Ranger
4x Huntmaster of the Fells
4x Immerwolf
4x Wolfir Avenger
4x Flames of the Firebrand
4x Prey Upon
4x Moonmist
1x Kessig Wolf Run
You'll need at least 4 lands that can produce both Red and Green. And I would probably like 8 of them, if possible.
