Add Spell Flux Effect For Ryze's Ultimate

All Spell Flux marked units (enemies and neutral) inside of his Ultimate warp zone (the are in which allies need to be in order to TP with him) at the time Ryze is warped, are warped as well.

This of course wouldn't help for engages since you will most likely not be near any enemy units, and you wouldn't really want to bring enemies together. (Maybe take a neutral monster in just for giggles, excluding Dragon and Baron of course) This could be useful for isolating enemies from the group, taking them out of position so they can't contribute in a team fight, and/or you use this to pick them off. The delay would make this challenging to accomplish since the enemy will most likely try to leave the zone if they know you're planning on marking them. A well timed Rune Prison > Spell Flux would make this easier. Sell Flux > Rune Prison would still be possible but more difficult because Rune Prison would consume the mark. You could potentially apply another mark if E comes off cooldown soon enough, or by last hitting a near by unit with an ability. This could also hurt you if you accidentally mark a target that you did not want to take with you. It would also give your enemy an incentive to dive on you when they see that they are marked and you are about to warp.

Question, does Ryze need to be inside of the zone for it to work? If he could activate the zone, mark and stun an enemy, then move out of the zone he would be able to tp them away and remain where he is, Or this could be used to tp allies out and stay.
