Canonically, How strong is Viktor now?

We've seen him take over a whole city in mere moments and, realistically speaking—he lost to plot.

How powerful would that make him compared to other champs though?

The most powerful thing I've seen him do is manipulate time (Alternate Viktor giving Jayce all those runes when he was a child) and his laser cutting thick steel. He can fly, probably telepathic, can make armies, and has enough combat skill to singlehandedly, and gracefully, outmanoeuver jayce in the council room.

I guess a baseline question for this discussion would be, would he beat his own Evolved Warwick?
