Honestly the provokes made this fight hard, not the actual boss. This was the second boss I actually had trouble with, (The first was boreal juggernaut).
I liked the onyx jaguar and wind runner, but didn't like how it made the decoys death machines with provoke.
I beat him with my very own creep deck I use for laddering, and used some Creep Juggernauts to distract him while I built up my creeps and then eventually got variax to win the game.
Another thing, he had decent AI. He prioritized taking out my abyssal crawlers and kelainos instead of just hitting me.
WHY DID YOU GIVE HIM GRINCHER?
He got cyclone mask and twin fang one of the times. Not fun. (The time I won he got a ghost azalea...)
Pretty decent boss though!
Also my orb gave me a zookong, how fitting.
