Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
From the OP:
Even with a free switch, Kingambit loses in the worst case, so it is not a check. With a manual switch, Klefki loses in the worst case (and not even the worst case; Roaring Moon just needs to get one prediction right and then tera, and it wins even with min rolls), so it's not a...
If Roaring Moon uses Earthquake on the switch, you lose. Earthquake plus two turns of Tera Flying Acrobatics is a KO after Sitrus Berry, and Acrobatics outdamages your Recycle healing.
I'm not sure if relying on Supreme Overlord is allowed, but relying on Sucker Punch definitely isn't. A check...

I'm not sure why everyone's talking about Dazzling when Armor Tail is competitively identical and almost certainly better flavor given our typing. I'm also fine with having Dazzling/Queenly Majesty/Armor Tail as a single item on the slate and choosing among those three in a future flavor stage...
Unburden could be good (depending on our speed and whether we have Clangorous Soul), as it gives us more speed for sweeping and gives us more incentive to use Throat Spray over Specs. I also think Armor Tail would be good so that priority can't stop our sweep.
This is the way Future Sight works if you target your ally and then switch places with them (at least on Showdown, I don't have a cartridge to test on), so it's probably not a bug.
