I just looked at the ones you suggested and all would be affinity friendly. Good call on that. Now which would be best is the question?  Skraank's A2: Attacks 1 enemy 2 times. Heals this Champion by 15% of their MAX HP on each critical hit.  Wondering if that may throw off the stun attack possibly. Looks like to me Rowan would be the best pick of the 3 but I may be missing something. Rowan by the calculator after building the rest of the team the highest hp I am going to get to is 29,000. My pain keeper is sitting at 36,000. Again a big thanks to all of you for what you do. 

I would go Rowan. Gonna be fairly easy to build and is a champ I think we want to have around at 60 too. We'll just pile poisons and that damage in there.

I was looking at Skraank too but that kit looks troublesome for tuning purposes.

Edit: missed your earlier reply about Skraank, sorry

Right but the highest I can get him on HP now is 29,000. Pain keeper is at  35,000 HP 1500 def. . man eater almost 30,000 HP 1900 DEF. fahrakin is at 27,500 1900 DEF . fayne is at 31,000 HP 1200 DEF. Not sure how low I can go on HP and Defense at the beginning and I know slowboi is supposed to be highest hp and lowest defense if I remember right. Of course that is with Rowan not leveled or ascended at the moment. Might change things. 

Would this be after 6'ing her?

Team finally got assembled, It is a highmythman comp with frozen banshee and fayne. Turned out to be a 3 key on unm. Close but it made it to 3 key. 

Congrats. :) Next time you finish a run drop a screenshot in here if you can. Would be great to see the what it all looks like at the end.

Thanks I will post one tonight after I run the 3rd key.

Yeah! Let's see the results of your hard work :)
