Sundial is counter-productive, as it stops your Ball Lightnings and Photons from doing any damage, and they're your main damage source. I'd take them out for 5/6 Animate Weapons and a Mark of W/E. Yes, it doesn't fit with the theme with the deck as much, but at least you'll be able to play more than one Dirk on later turns. I mean, Sundials can use the Light quanta for their ability, so why can't you use Animates, too?
Otherwise, this is more or less a fun deck - anti-Devourer/anti-Black Hole, too.
