Vigilance
Geist-Honored Monk's power and toughness are each equal to the number of creatures you control.
When Geist-Honored Monk enters the battlefield, create two 1/1 white Spirit creature tokens with flying.
As long as Geist-Honored Monk is on the battlefield, its second ability will count itself.
The ability that defines Geist-Honored Monk’s power and toughness works in all zones, not just the battlefield.
