I like beastmen. They aren't stellar, but they have their place. Consider that "Dash" is effectively a "Frenzy" for a beastman (enables move, attack, attack), and if your monster is already in position, "Frenzy" is even better (attack x3.) Don't forget that the master also reduces the chance of each nearby minion missing from 1/6 to 1/36. Additionally, the OL could also use the Unseen Wings reward to move them into striking range, or a master sorcerer's summon.
I think the "bloody rage" ability sounds way too devastating. With the right combination of Dash and Frenzy cards, you could have the group dishing out 10-12 attacks in a single turn, with the miss chance on each attack being 1/36. That's absurdly powerful.
