BigShot Jazz Jhin

This composition is the strongest by far. However, this composition needs a few 5-cost units, which is not easy. That's why, to get the maximum potential, the ideal would be to reach level 9 as soon as possible. Nonetheless, this composition have one of the best ealy-mid games of all, since Jazz is currently the strongest trait. It should be noted that there is no specific positioning, beyond positioning your tanks in front and the carries in back (if you are fighting against Akali it's highly recommended to put the jhin in the middle to not get the focus).

The best augments you can have are Cybernetic and Combat Augments. Furthermore, the augments that give you items are not bad because you will have more than one tank, and the items that you may have left over from Ad can go in Ezreal or Lucian. Additionally, it is important to emphasize that because this is a comp of level 9, all the augments that give you money or experience, are very interesting (you should never have 3 augments of this type, one or maybe two are fine, but no more).

Jhin needs one mana item, Blue Buff or Spear of Shojin, and two damage items, Deathblade and Guardbreaker or Giant Slayer. Illaoi will carry the tank items, and the two best are Steadfast Heart and Redemption or Warmog's Armor. Yorick will be the off-tank holder, with items like Hand of Justice or Bloodthirster and Sterak's Gage or Titan's Resolve. Other interesting items would be the Sunfire Cape since it is very good in early and reducing the healing of the enemies is very relevant, and Last Whisper since reducing Armor is very good (it is advisable to put this item on another unit than Jhin).

To play this composition, you need Bard headliner +1 Jazz (+1 Dazzler is not so bad) or Miss Fortune headliner +1 Jazz, and then just play Superfan (at level 5 you play another Jazz and at level 6 Ekko).

Already at level 7, you just play Kai'Sa. At this moment, you have to take a decision:

1. Play Bard 3-star and Miss Fortune 3-star. This option is more safe, but it's a bit worse. You will just stay at level 7 to Slowroll and find 3-star units. The most important ones are Bard and Miss Fortune, but if you can also get Kai'Sa, Neeko or Ekko 3 is very good. If you want, when you finally get your 3-star units, you level up and play Lucian (to get more value of Jazz) or Ziggs (to get two more traits).
2. Push levels up to level 9 and play the Jhin comp. This option is more risky, but if you achieve it is the best comp. At level 8 you will just play Lucian (to get more value of Jazz) or Ziggs (to get two more traits). And, at level 9, is when you fully direct your composition towards the final table.
