War of the Spark

If you don't control another creature with power 4 or greater immediately after Turret Ogre enters the battlefield, its ability doesn't trigger, even if you can raise a creature's power right away. If you control no other creature with power 4 or greater as the ability resolves, nothing happens. These don't have to be the same creature, though.
