Happy New Year and Merry Christmas!
Why do you use the one-shot build but not the rabadon build in the core? If there are too many core slots, then it would be logical to remove Zhonya's Hourglass from the list, after that you will be more squishy and defenseless, but there will be a real one-shot, otherwise there may not be enough damage.
And so, an interesting fresh look at the champion!)
