Specifically, I have 5 Grey Knights, 3 with nemesis force swords, 1 with psilencer, 1 with nemesis daemon hammer. I have 12 Necron Warriors 2/ green tubes, and 5 Immortals with gauss blasters. Finally, I have 8 Dark Eldar Wyches, with wargear that is in no way suitable for tabletop; they were gifts, so I goofed around with them.
I'm looking for Chaos Space Marines, specifically Obliterators or Cult Squads, but I will take money, 50% value, less on Dark Eldar.
