Dracolich

Flying
When Dracolich enters the battlefield, put a colorless Phylactery artifact token with Hexproof, "This artifact cannot leave its owner's control", and "This artifact cannot be returned to its owner's hand" onto the battlefield.
Whenever you control no Phylacteries, sacrifice Dracolich.
You may cast Dracolich from your graveyard for {2}{b} as long as you control a Phylactery.
