tips on how to solo N4 as Punisher? I didn't think it would be this hard. I buy red cards, purple dmg & dmg resist, and life steal when I see them? What am I doing wrong? Should I be using the random slot more?

Also, is there a trick for NOT getting bubbled by Namor or breaking out of it faster? I keep shooting so the life steal keeps me alive, but then I just get dropped into zombies and insta die. I've wasted two nights in this and I'm about over it. Do I just need to spam revives at this point?
