Games Workshop sent the four USA 2006 Slayer Sword winners an Orc Warboss sprue. They could only use the pieces on the sprue and green stuff, and other non mini relayed items like plasticard for the competition. The coverage is in US White Dwarf 325, But you can vote for the mini you like best to decide the winner!!!!
