This is a list I thought up while working on something else, but it might be fun to run. It has such a high bid because I'll either be slotting Boba into Frost's place and/or future proofing the points increase that Han Gunner and Marauder should be getting. Thoughts?

Koshka Frost (71)
Trick Shot (1)
Marauder (3)
Han Solo (Scum) (4)

Outer Rim Pioneer (24)
Crack Shot (1)
Tactical Officer (2)

Captain Seevor (28)
Trick Shot (1)

Mining Guild Surveyor (25)
Trick Shot (1)

Mining Guild Surveyor (25)
Trick Shot (1)

Total: 187

I like the combo of outer rim pioneer and mining guild tie. Play it myself, gives good options.

Seevor has a good ability. Bringing him to higher effective initiative would be nice, but it is not possible with this list (Torkil mux being the obvious choice but not legal). Still, he has the highest initiative in your list so his ability is useful for shredding.

I wonder if there is a way to deal stress, to capitalize on koshka. But I don't know how.

Be prepared to lose one or two ties early. So try to coordinate focus evade on the most obvious target in the initial engagement.

If you swap out for Boba, putting Swarm Tactics on him might be worthwhile with Seevor in the list.
