Ardyn, the Usurper

Except for the listed exceptions, the token copies exactly what was printed on the original card and nothing else. It doesn't copy any information about the object the card was before it was put into a graveyard.

If a card copied by the token had any "when [this permanent] enters" abilities, the token also has those abilities, and they'll trigger when it's created. Similarly, any "as [this permanent] enters" or "[this permanent] enters with" abilities that the token has copied will also work.

If the copied card has {X} in its mana cost, X is 0.

The token is a Demon creature instead of its other types and is black instead of its other colors. Its base power and toughness are 5/5. These are copiable values of the token that other effects may copy.
