Rule 706.1
Official source text from the 29 September 2017 Rules release
Some objects become or turn another object into a “copy” of a spell, permanent, or card. Some effects create a token that’s a copy of another object. (Certain older cards were printed with the phrase “search for a copy.” This section doesn’t cover those cards, which have received new text in the Oracle card reference.)
