Your build has way too much cooldown reduction. Your items give you 35% (with full stacks from soulstealer), your masteries give 9%, and runes give.... uhh, 8% ish i think? Either way, that's well above the 40% cap, and Kassadin is insanely mana hungry, so you should get blue buff whenever you can. I personally recommend getting mana regen/5 per level seals and either AP per level glyphs, or stick with cooldown reduction if you don't get any cooldown reduction items in your build.

To replace soulstealer and frozen heart, i recommend a deathcap and Zhonya's hourglass.

One more thing... don't get trinity force if you're dominating, get lichbane. If you're doing very well, you can end up with some hilarious results. ;)
