Last known information about an object is immutable - it cannot be altered. Rules and effects that would modify the object that no longer exists do not modify the last known information about an object; this may cause effects to fail.

Example: Luminaris has the text “If there is a yellow card in your pitch zone, your Illusionist attacks get go again.” If you controlled an Illusionist attack as a chain link on the combat chain, but it was removed, and then you put a yellow card in your pitch zone to meet Luminaris’ condition, the chain link does not have go again because the last known information about the attack cannot be altered.
