Do the advanced colonies in Sidereal Confluence: Proliferation change by round, and which set is used when?
The designer's rules text for the advanced colonies sets out the round-by-round sets.

Yes. Round 1 uses the original colonies, rounds 2 and 3 use the B colonies, and round 4 onward uses the C colonies. Unowned colonies are discarded between rounds. Each faction that starts with a colony gets a random original colony, except Unity, which takes one of three random B colonies.
