Introduction
This composition is a variant of the Ahri carry comp, and has very good results in general. To get the maximum potential, the ideal would be to reach level 8 as soon as possible with 50 gold to be able to get Ahri and your tanks at level 2. It should be noted that there is no specific positioning, beyond positioning your tanks in front, and the Spellweaver units behind.
Augments
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 Ap can go in Lulu or Seraphine. Additionally, it is important to emphasize that because of being a Fast Level 8 composition, any augment that gives you experience or economy is really good (you should never have 3 augments of this type, one or maybe two are fine, but no more).
Best Augments
Items
Twisted Fate carry Ap items. The Blue Buff is his best item, and then the best are the Nashor's Tooth and Hextech Gunblade or Giant Slayer (these two items can be exchanged). Tank items, whenever possible, go into Blitzcrank before Ekko or Mordekaiser (except in situations of not getting Blitzcrank level 2). 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, Thief's Gloves since it is generally good, and Ionic Spark or Statikk Shiv since reducing Magic Resistance is very good (it is advisable to put this item on another unit than Ahri). Finally, for Sona the best items are Guinsoo's Rageblade and Spear of Shojin.

Early-Mid Game
To play this composition, no specific headliner or champion is required at the beginning, since the objective is to set up the strongest possible comp and push levels. The best start would be Annie Headliner with Superfan (at level 5 you play Seraphine or any other Spellweaver unit, and at level 6 you play Ekko or any Sentinel unit).

Late Game
Already at level 7, is when you fully direct your composition towards the final table. Here, depending on your life and how strong your table is, you can consider changing the headliner you have for one of cost 3 (which will be very likely to come out at this level), roll a little to stabilize or saving to go up to the 8 (this is the most recommended, but there are games where this will not be possible). When you reach level 8, simply roll until you have your entire table level 2, looking for the Caitlyn headliner Blitzcrank preferably. If you find Blitzcrank 2-star before Blitzcrank headliner, you will look for Ahri headliner. When you get your units to 2-stars, it is highly recommended to go up to level 9 to get 5 Spellweaver
