Unkillable Sentinel Ahri

https://www.tacter.com/tft/guides/a-pro-player-hard-forced-this-comp-for-1000lp-in-4-days-ae8b1095

This comp uses the overpowered frontline of 6 Sentinel to buy time for Ahri and Sona to scale up with Spellweavers.

Sentintel headliners are great to play around early since they encourage you to hold more Sentinels. Corki is a great item holder since he synergizes with the board. Other item holders that are great - Annie (if you have mana item), Senna (broken), Kaisa, Aphelios

This board is highly flexible mid game with all the synergies that Ekko and KDA open up. You can easily play more into Spellweavers, Emo, Superafn, True Damage, etc.
