Fumikage Tokoyami

When Fumikage Tokoyami enters the battlefield,
and at the beginning of each upkeep, create a
legendary creature token named Dark Shadow,
whose power and toughness are equal to your devotion to black, with flying, shadow, vigilance,
and {t}: until end of turn give Fumikage
Tokoyami flying and +X/+X, where X equals
Dark Shadow's Power.
"It is our fate to crush each other." - Fumikage
