Dorian Gray, Ageless Hedonist

Indestructible
When Dorian Gray, Ageless Hedonist enters
the battlefield, create The Picture of Dorian
Gray, a colorless legendary artifact token with hexproof and "Whenever a creature you
control named Dorian Gray, Ageless Hedonist attacks, put two age counters on this."
If an artifact you control named The Picture
of Dorian Gray would leave the battlefield,
instead remove all age counters and sacrifice
Dorian Gray.
