Rule 612.5
Official source text from the 15 July 2011 Rules release
One card (Volrath's Shapeshifter) states that an object has the "full text" of another object. This changes not just the text that appears in the object's text box and type line, but also changes the text that represents its name, mana cost, expansion symbol, power, and toughness.
