Here's an old mono-Scum deck that I used to run:
x2 New Jabba, Xizor, Dengar, Pilot Boba
x1 IDYLE, Hunters
Honestly I think you may be limiting yourself a bit too much by that thematic restriction because Xizor is one of the best Scum pods in the game and I'm a huge fan of IDLYE as well. To start, I'd take the above deck and swap out the two one-ofs with Jabba's Palace.
So the tricky problem with Scum is that they have a weird resource curve; good pods with 1/1 resources aren't easy to come by in mono-Green decks and in the deck I recommended you don't have any at all. I've always gotten around that by cramming my deck with lots of 2-resource objectives. Having four more or less guarantees that you'll draw into at least 1 on the objective flop while having six guarantees that you'll draw into at least 2. Six resources means you can play a 2/1 resource and an Elite 5-cost unit (Jabba or Xizor) on T1. If you can get the big guys out then you don't need a lot of resources on your second turn (remember, Captured only costs 3).
In terms of synergy, Pilot Boba is kind of the odd one out but thematically he's a definite inclusion. But doubling up on him gives me two more 2-resource objectives, 2 more uniques I can use for Scheme, more resources, a high edge count and Boba is versatile as both a unit and a pilot.
Also, I'd totally recommend using the Replacement cards here. I'd swap the Debt Collector in Xizor's pod with It's Beautiful and the Weequay for Aurra Sing. The Debt Collector is garbage (and having eight 2/1s is really too much) and I've had a huge amount of success using It's Beautiful in its place in another deck I've been using. As for Aurra, unfortunately while you're right in that Jabba's Palace is an extremely powerful enhancement it's in a pretty poor pod and even if you're running a Capture-oriented deck you really don't need 4 Weequay Elites. Aurra isn't a great T1 unit but she gives the pod a bump in pips that it drastically needed and she's a versatile closer.
So yeah, there's a thematic deck with a good amount of Capture synergy. What do you think? Also, please keep your posts coming because it's great to talk about the game! I hope you make more topics soon.
