The key here is balance. Consider current champion power levels as a guideline, not a baseline. You've effectively build her with 5 ults:

Shadow Orbs: To clarify; are you saying that casting a non-ult will grant her AP forever; or are you saying that she gets +3AP per shard (3 per orb) as a pasive buff, to a maximum of 27AP at level 1 (81AP at 18)? Because both of those are very OP. The latter would get her that much AP without a single item. If the former is true, build CD on her and you're snowballing at a rate of 10AP every 3 seconds. Ignoring the AP ratios, that's mental. Consider Veigar's Q for balance reasons; it's 1AP per kill for a reason. And completely ignoring her abilities, I heard she liked Sheen and Lich Bane; because even with simply 81 bonus AP, that stings. 4 digits AP? 1-shot. +15 when she ults...

Mirror shield: Makes Vlad very unhappy. And Twitch dislikes pressing his expunge button. Negates so many ults its unfunny. There's a reason QuickSilverSash and Cleanse have global CD. And they only remove current debuffs, at a cost of a summoner spell or 1640g. With a 90/120s cooldown.

Dark apparition: Just consider this: Empowered, cast on Veigar (for instance) ulting their AP carry at the back of a teamfight. 3x his ult damage to their AP; 2x damage of the AP champ's AP to their whole team, plus flat magic damage, plus a ratio of that AP.

Ritual of displacement: Empowered, that's practically Oriana's ult. Which has a 90 second CD. And you can pull that off about 5x as often. Without being an Ult. Admittedly dealt as a damage-over-time, but still.
