Sometimes, simplicity is a beauty itself.

I'd suggest E to just steal a percentage of the target's attack speed as her own instead of a random ability buff, as ability buffs don't always exist in every game, even if they do, it's a headache to decide. Do mention a range though.

Secondly, a mana champion would definitely stack mana, so what's with the low mana costs? A mana champion like would have 160 per cast on his Q if you noticed.
