You may have this creature enter as a copy of any creature card in a graveyard that was put there from the battlefield this turn, except it's a Phyrexian in addition to its other types.

You don't have to choose a card to copy. If you don't, Activated Sleeper enters the battlefield as a 0/0 creature and is probably put into your graveyard immediately, unless something is increasing its toughness to keep it alive.

Treat Activated Sleeper as though it were the chosen card entering the battlefield, except it's also a Phyrexian. Any "As this creature enters the battlefield," "This creature enters the battlefield with," and "When this creature enters the battlefield" abilities of the chosen card will work.

If the chosen creature card has in its mana cost, X is considered to be zero.
