I'm very excited to try out this archetype. Seems very promising as a more control-oriented Hunter with real finishing power as well.
Beast Draw Cards with Encumbered Pack Mule I think can add an interesting line of defense while you build up your questline. All of the damaging spells are cheap removal, so they work perfectly with Kolkar Pack Runner, which has already proven itself a great card. Professor Slate may not prove necessary, but I'd like to try him out. Barak Kodobane no longer needs to be paired with Mankrik as we now have a 3-cost spell that we want to draw in Aimed Shot.
Let me know what you think!
