Phantasmal Sphere

Flying

At the beginning of your upkeep, put a +1/+1 counter on Phantasmal Sphere, then sacrifice Phantasmal Sphere unless you pay [1] for each +1/+1 counter on it.

When Phantasmal Sphere leaves the battlefield, target opponent puts a blue Orb creature token with flying onto the battlefield. That creature's power and toughness are each equal to the number of +1/+1 counters on Phantasmal Sphere.
