Hmm, blink or displacement essentially automatically generates a 75% combined miss chance. Powerful. OTOH, the wizard is astrally projecting in a level.

Aesthetically, the abilities don't yet feel well-linked to one another; ditto with the spell list. It's just a collection of good spells and good features. On the other hand, the lack of specific flavor allows the class to be bent towards a variety of different character styles -- it's like the tofu of base classes.
