Chimeric Sphere

A noncreature permanent that turns into a creature can attack, and its abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn’t matter how long the permanent has been a creature.

If the first ability is activated and resolves, then the second ability is activated and resolves, Chimeric Sphere will be a 3/2 creature. It won’t have flying.
