The Assassin Coven composition in Teamfight Tactics is one of the strongest deck in Patch 11.11 with LeBlanc and Volibear as carry.
Patch 11.11 went live on Thursday. Various changes in meta has been made through the patch including the massive buffs for Dawnbringers and changes to shadow items. There has been a buff for Morgana, and no Assassin or Revenant champion has been nerfed.
This has been great merit for the Coven Assassin composition. With the most recent patch, it has climbed as one of the most OP decks.
TFT Patch 11.11 Coven Assassin Guide
According to LoL Chess GG, the Coven Assassin deck currently has a 20.5% win rate and a 71.2% chance of staying at the top 4. It is the top three Meta trends for Diamond and above players.
Key champions include LeBlanc, Volibear, and Katarina. Volibear has received a buff this patch as well as Morgana. Morgana and Lissandra will be the ones up front as the tanks while the rest jump into the other team.
The strength of the build is the great amount of damage of LeBlanc, Katarina, and Nocture and sustainability late game from the Revenant characters such as Ivern and Volibear.
If you are having trouble following the direct build, you may pivot the build by making Nocturne the carry or replacing one of the assassins with Viego as well. Yet make sure that you are collecting critical damage items because that will be your main source of damage.
