You could credibly make Animate Object an Alternate Power of Transmute, of course, but that's not an option for me, because Transmute is already an Alternate Power of my magic pool.
So none of us have any tech-targeted attacks, really. Though we have attacks that aren't any less effective on tech.
Anyway...just pointing out that, say, because you hit a robot with a water blast that doesn't mean you can then expect a short circuit. The GM might decide it does, but he's under no compulsion to do so unless you specifically bought an additional power for your blast that does extra damage (or causes effects on) to technology.
