Vertical Exotech Patch 25.12

Vertical Exotech was severely buffed in Patch 14.6, making it the strongest vertical trait in the current set. With Jhin 2* also getting buffed to the point where he is the strongest 2 cost in the game, it's very easy to pilot this line by staying within the vertical trait.

Your Exotech item priority is listed below. Generally, as long as you do not have a Cybercoil, the line is playable. Cybercoil is just too weak relative to all of the other Exotech items.
For Zeri: Pulse > Flux
For Varus: Fang > Holobow
For Mordekaiser: Chassis > Lantern >>> Cybercoil
For Sejuani: Cybercoil > Lantern

One of the biggest mistakes players make when playing Exotech is itemizing Sejuani as their main tank. Mordekaiser 2* is actually tankier than Sejuani 2*, but since Sejuani provides such invaluable CC (Crowd control) with her ability, you only really want to itemize her with mana-tank items such as Protector's Vow or Adaptive Helm. Make sure to position Sejuani A2 or A6 (2nd to the right or left in the first row) to snipe your opponent's carry in the corner with her stun.

Additional pointers:
1. If you have Corrupted Chassis as one of your Exotech items, and you find a Vanguard emblem, make sure to use the Vanguard emblem + Chassis on Mordekaiser. This is a very broken interaction that doesn't even require you to have 2 Vanguard activated. 3rd item is ideally Warmog's or Crownguard.
2. You can position Jhin and Kindred in the 3rd row instead as depicted, so that Zeri dashes around in the 4th row instead of jumping up to the 3rd row.
3. Flickerblade on Zeri is broken. If you find the artifact, you can consider playing this line heavily.
4. Guinsoo + Kraken + Pulse > Guinsoo + Pulse + Flux, but the latter is still solid.
