SUPER Fun/Kinda working Jhin Support

Hey guys, recently I've been dropping some time into this Jhin support idea I had. The basis is you are a tanky disruptor with perma slows and burst. Let's break it down-

So first for masteries, I ALWAYS take Insight, and then either deathfire or grasp.

For summoners always take exhaust and flash.

Now for the build. Start relic and refillable. You rush iceborn, then boots, then black cleaver. Next, you buy these in any order- iceborn, steraks, gunblade. In lane you are SO annoying once you have sheen/iceborn and you can literally win trades against ADC. Once you have other items, you can see where it all ties together- you have a sweet HP pool, perma slows, armor shred, gunblade burst, and respectable AD. This build is so damn fun, if you try it please tell me how it went.
