Pirated Copy

Any enters-the-battlefield abilities of the copied creature will trigger when Pirated Copy enters the battlefield. Any "as [this creature] enters the battlefield" or "[this creature] enters the battlefield with" abilities of the chosen creature will also work.

You can choose to not copy anything. In that case, Pirated Copy enters the battlefield as a 0/0 Shapeshifter Pirate creature, and will probably die almost immediately, when state-based actions are next performed.

Being a Pirate and having the granted ability are part of the copiable values of Pirated Copy. If another creature enters the battlefield as or becomes a copy of Pirated Copy, it will copy whatever Pirated Copy is copying, be a Pirate in addition to its other types, and have "Whenever this creature or another creature with the same name deals combat damage to a player, you draw a card."

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

Pirated Copy's ability doesn't target the creature.

If the chosen creature is a token, Pirated Copy copies the original characteristics of that token as stated by the effect that put the token onto the battlefield. Pirated Copy is not a token, even when copying one.
