Super easy araj kill with actual low leveled minis (18.3 avg level)

Just threw this deck together to show this guy getting killed without using level 23 minis. It's the first deck that came to mind so it's far from being optimal. i missed the summoning stone on my worgen deploy, missed the cheat death on the quillboar and still killed him in 1 attempt.

Adjust your deck as needed to get a good start. It's easy stuff. Big key here is using resistant quillboar as a tank instead of armored earth ele ;)
