I've only been doing 25ss scraps so far, but here's my preferred lineup:
Ramos
Joss - 9 ss
Rusty Alyce - 10 ss
2 Arachnids - 6 ss
I love Alyce over Borgy because, though Borg has that nice 5 movement, I don't like how easy of a target he is. I may be playing him wrong, but every time I've used him he's gone down pretty fast.
Alyce can deal a ranged beating, and she also has some nice defenses: (Bag of Tricks: Misdirection for the win; Boobytraps if Ramos had activated first this turn and my opponent is closing in; Snares if I'm up against a melee-happy charge-tastic team). Also, she can reactivate your constructs with no penalty until the Start Closing Phase; just be sure to heal them up on the next turn! I do want to pick up a Steampunk Abomination
The big deal-seller with her, as been stated, is her Something to Live For ability. Those two extra Fate cards is a higher chance that Ramos will be able to summon a Spider or Elec Creation that turn without burning soulstones.
I can't wait to do bigger scraps; 25ss sounds very limiting to Ramos, but that should all change when I pick up a C. Hoffman boxset and add those constructs to the arsenal.
