I agree with xdude, but take out two or three Adrenalines and replace them with some kind of healing.
What is this for, AI3, AI5?
Also, you need to focus on just 2 elements, if its poison you are going for since the offense is really lacking.
3*4=12 damage a turn, plus 2 poison counters. You get 12 poison counters from the Deadly Poisons, and 1 a turn from Arsenic. Add all that up, you get 12+(2*however many turns)+(1*however many turns)= total poison damage.
Assuming AI5, you can probably expect 20 turns for the poison to kill. So using the above formula, 12+(2*20)+(1*20)= 12+40+20=12+60=72 poison counters.
Hope this helps, and sorry if I confuse you, my brain is hyper on coffee.
