Core (Tinker) is busted, here's why

Core Tinker (and Tinker in general) is busted and I'll explain why

First we have to understand that he is Tinker.

Each time Tinker casts a spell, at least one enemy player gets tilted.

You buy shard instantly at minute 15. By this time you'll have not only the enemy team reporting you, but also your team for buying Tinker shard first.

[spell -> rearm -> spell again]

Laser (damage -> REARMING -> damage again)

Shield (prevent damage -> REARMING -> prevent damage again)

March of the machines (area damage (ally heal) -> REARMING -> area damage (ally heal) again)

Rearm (Rearm -> REARMING -> Rearm (teammate that saw you do this reports you for griefing) )

Right click (attack -> REARM -> attack again)

You're looking at roughly 2.2k behavior score damage before the game ends at minute 25 because your team is tilted.

Keep in mind this is all without typing once in chat. This is seriously insane by any means.

Items like vessel or radiance sometimes proc reports, just in case you wondered.

Now for itemization it is essential to get a boots of travel at minute 12 to the second. This is because they will never expect you to have a second teleport as soon as they stun you out of your first one. As Pos 1 you can mute your team for peaceful farming. Chatwheel voicelines are essential in most games at some point, because you are a Tinker that is very likely banned from typing in chat. Now for damage you can obviously go for Aghanim and optionally Kaya. Dagon is also an insane item because it's like your laser, but red. I also want to shout out E-Blade even if it sounds kinda anti-synergistic with right clicking. Core Tinker’s biggest counters are carries that jump you with BKB. BKB nullifies almost all of your damage. So self-casting E-Blade to buy time is very valuable.

The cast range also helps immensely with positioning for a good BLINK DAGGER to safely close the distance, attack and retreat/kite away. One dagon with full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and more full spell rotation followed by REARM and dagon will kill basically any hero without BKB, especially at level 25. I haven’t found “the build” yet, but these are the items I found to be very effective. I also tried radiance, for example, but found it to be difficult to queue for the next game as my behavior score took a big hit. I also played against AM once. I thought it was going to be a hard game, but that AM picking AM while being assigned Hard Support completely solved that situation and he melted like every other hero.

I am a little bit surprised this hero wasn't flexed to pos 2 in pro games yet. I can see why pos 1 wouldn't be good as he is immensely countered by BKB.
