Even using Trish over Naja Ld, your deck is going to be extremely vulnerable to SoA. I'd choose Jane Ramba for your 3*, or either Laura or Archibald if you can't afford Jane.
For your 4* cards, I'd recommend taking Gatline over either Chiro or Burger to give you some more stability and some attack manip.
For 2*s, the safe way to play it is 2 round winners and a throw away. Winston's your throw away (you'll have to ditch him in freaks weeks), so you get to pick 2 of: wardog, dean, victoria, and thorimund, depending on your preferences. Since your deck is not low on damage, Thorimund is a very strong pick. My second pick tends to be Victoria, since she can guarantee wins against SoA, but if you'd rather use dean or Wardog, for their high potential or higher stability, that choice is totally up to you.
