Ok either i'm really tired, or my reading comprehension just went down by a factor of 1000. The first cast works exactly as the live one, using the innate and casted spheres alike, but when she gets the first kill and recast window, she won't have anymore innate spheres and can only work with ones already on the field (for discussion purposes let's say 5), she casts another Q and casts a second ultimate with the 6 spheres, casts an additional sphere or 2 after that and refreshes the spheres with an AOE stun and gets an 8 sphere ultimate and so on. Since her Q bonus causes her Spheres to constantly refresh on ability casts that use the Spheres to begin with, of she chains them correctly, she can main the Spheres for a large period of time, while adding new ones. After the recast window is over and her ultimate goes on CD, the spheres re-appear floating around her ready to be deployed at a latter time. I think that's what you mean.
