Beastmaster Leoroxx shines will all the new Big Beasts stuff that Hunter got, things like Wing Commander Ichman, Vanndar Stormpike, Mountain Bear, and Humongous Owl.

This deck stalls early aggression with Secrets, both from deck and from Rinling's Rifle, before going absolutely nuts in the late game with Big Beast after Big Beast (with Jewel of N'Zoth and Revive Pet added in for good measure).
