I disagree. His deck is extremely different, and if you don't mind my saying, far better.
The scorpion's poison is a far more consistent form of damage, you don't have to worry about getting counter controlled. This deck plays a lot more like a stall, with heals and control. Your deck plays like a rush.
I really like this design, it's got nice synergy. I might try playing it.
After some testing, -1 adrenaline +1 scorp works better. I got decked out by basic stall because I couldn't keep enough scorpions alive. Adrenaline only gives you one more poison, having more creatures is better, in my humble opinion.
