Maybe I will sound like repeating myself but … killed on first try with Undying Abyssian.
Was funny as I usually keep a Vorpal Reaver in hand on first turn to feed my Unseven but with this boss, it was a pleasure to chain cast Vorpal, SpecRev etc on early game 
It’s tempting to make a deck full of fatties with 8 and 9 mana cost minions and spells …
turn 1: juggernaut.
turn 3: win
Turn 1 juggernaut is OP. I actually repleced it in my first attempt because i mistakenly assumed that i would have a curve
You been lucky, I tried 4 times, Juggernaut turn 1 and every time he had a Martyrdom ready for it 
Side-note for Magmar :
Very refreshing to start turn 1 with Decimus+Tectonic+Gaze 
or … that
Edit : he also had a Martyrdom for my Turn 1 Valknu Twin
Edit 2 : ok, finally on 6th try, I managed to get a Turn 1 Juggernaut stick \o/
Wow, he only used martyr once on me across several games and that was when i got one of his eclipse from… something… in my dying abyssian deck
There are some funny combos with Vanar too : Embla T1, AotMountain T2 
Really funny boss for goofy tests, I 
it
… make it double Mountain !
This boss was absolutely beautiful. Went in with a vanar deck I was testing, realized that I started with 9 mana, conceded, then went back in with a janky vetruvian deck to win with Dank Nem
I Was looking throught that challenge thread and now i have to try this boss with arcane devourer and ALL of the high cost minions
No, you used a camera instead of screen capture.
Dat fractal meltdown tho
It is my belief, at least in part, that this boss was designed to allow us to play all of our beefcake super minions that really never get to see any action in the current meta (or any, as the game is designed to end quickly).
33 mana play for 8! Seems legit.
How to be good 101.
Forget those big minions. I beat this poor fellow in 2 turns with dance of memes 
It could probably happen in 1 but I didn’t feel like trying again lol
Yes it does, I confirm 
This boss was really fun! Sajj doesn’t have to wait until late game to equip all those expensive artifacts, and the fact that he uses Grimes makes everything even better!
