Taking this to a more extreme then probably what your saying...
But SV feels like it has no synergy at all... WITH ITSELF...
I feel like it is getting better. One of my initial problems with it was that the sets didn't have internal consistency. Why doesn't Jabba not have Bounty? Why is Reversal of Fate not with Boba Fett? Why do the sets that key of capture either through objectives or units not actually have any capture (Jabba, Slave 1). Stuff like that.
But I feel like Slimy Scheme works within itself and helps boost other parts of Scum. The Hunters as well, though again the more unit capture from units or black sun you have then the better The Hunters is. Xixor seems like a pretty solid pod in general. His objective can give you an early resource ramp for a turn.
There is definitely a puzzle to building Scum. Some of the objectives are so useful that you want to draw them, but the pods are lacking. Some things are needed to combo together. It's definitely not easy.
I agree 100%.
But how about we put them where they make sense?
SV has the worst resource placement of any faction.
This is a solid reason why Scum deck building is hard.
I do like the Slimy Scheme placement (because I really like that objective). Jabba also has one though I wish he had the Weequay one and they had more capture. Also I'm not entirely sure Jabba is strong enough to make it to a deck. I like the double black tactics but the Sail Barge is too expensive for its ability (it should just straight up remove for 3).
They have some interesting unit resource options like Bib and the Outer Rim guys but they are all pretty expensive. That said if you are playing a Tatooine Deck with Slimy Scheme the Sarlaac Pit is some awesome resource ramping because you can heal your objectives with the Gamoreans.
The only set with Prized Possession in it unlikely to see play is the Carbonite Transport. Scum also has the Force Resource in the most playable set compared to the others (barely edges out Sith).
While I agree that Slave Trade is an awesome objective and the Force Resource is highly playable because of that I don't see it as a strong contender in a Scum deck, or maybe that it is just so much better in a Sith deck. Slave Trade really needs to win both the force struggle (at least on their turn) and edge (to enable the white tactics) which Sith are much better at doing than Scum. Maybe some of the new sets can help with that, Xixor certainly does by being Elite and having that edge card, but I still think Slave Trade is tool for Sith more than it is for Scum. That might just be that to get all the synergies of Scum working together there just isn't room for arguably their best objective.
