All versions of Sahilee esstenyially ignore the ensoul artifact. They make copies, copies only have the copiable values which include anything printed on the card and things that are the result if other copy effects. So Rai makes a copy of whatever is ensouled ignoring the ensoul. Sublime turns a artifact into a copy of the ensouled artifact as though it wasn't ensouled. Alternatively she turns the ensouled artifact into a copy of another artifact except it is still a 5/5 artifact creature.
Rule 706.2: When copying an object, the copy acquires (…) the values derived from the text printed on the object (…) as modified by other copy effects (...). Other effects (…) are not copied.
I can't figure out what either saheeli does to an ensouled artifact ensoul artifact
saheeli rai does her -2 make a 5/5 artifact copy of what ever ensoul was enchanting?
saheeli, sublime artificier does she turn one of her tokens into a 5/5 copy?
does her abilities carry over the 5/5 aspect of what ever artifact ensoul artifact is enchanting?
