[Buying]  [PLA] Looking for Sub-Attack Rings

For context, I have four Attack Rings that are compatible with Sub-ARs (Specifically War Lion, War Bear, Great Dragon, and Dark Wing), but I don't actually own any Sub-Attack Rings to use with them, leaving them as illegal parts for tournament play. So I'm asking for any spare Sub-ARs that you may have.
Here are the ones that are High-Priority:
  • War Lion SAR: Pretty much the one I need the most. It lines up well on War Lion, and exposes the contact points on Great Dragon, and on Dark Wing
  • Dragon Saucer SAR: The best of the SARs defensively speaking, I'd be glad to have a copy in my collection.
Alternatively, here are ones that less important, but that I'd still like
  • War Monkey SAR: Much less important. It'll only really work on War Lion because of its defensive nature.
  • Ark Pyramid SAR or Dark Wing SAR: Only compatible with Dark Wing because they're all three-sided.
  • Screw Zeus: The most offensively-oriented Sub-Attack Rings, but it's also rare as heck. If you're willing to part ways with it I'd be glad to accept it, but I doubt y'all would get rid of a Screw Zeus to easily.
