Hey! I am Frobei, I have been Challenger multiple sets in a row and I've been making TFT guides for years so stick around or follow me for more content!
Here is the list of the 5 most broken comps for patch 14.7, the first patch of Set 11. Also for each comp, I link a more in-depth guide so you can either use this article as a cheat sheet or use the guides as a support to help you learn more about the game!
TRICKSHOT KAISA






































Kaisa & Xayah received a buff while this comp was already strong in patch 14.6. Expect this comp to be S tier and overly contested. Check how to play it here: https://www.tacter.com/tft/guides/how-to-play-trickshot-kaisa-set-11-challenger-guide-d5853439
YONE HEAVENLY






























This is by far the best version to play Yone reroll, if you have a Heavenly Emblem or Reaper Emblem this is even stronger Check how to play it here: https://www.tacter.com/tft/guides/how-to-play-yone-heavenly-set-11-challenger-guide-5859f19c
DUELIST TRISTANA





























Another 3 cost reroll but this time it's with Tristana and Volibear. This comp also has a great late game cap with many 4 cost and 5 cost who can become secondary carries (Irelia, Lee Sin, Rakan and Wukong).

SENNA GHOSLTY































This comp is still going to be strong because it didn't get only nerfs. Inkshadow received buffs and Morgana as well.

ARCANIST PORCELAIN REROLL

































Arcanist and Lux received buffs in patch 14.7. This comp struggled against some match-ups but its natural counters received nerfs. Expect this comp to be a bit niche but powerful when played properly.
I suggest to go for this comp if you have a Porcelain emblem.

(Bonus) SORAKA DIANA REROLL


































With Diana & Soraka buff we can see this comp being popular as it was during PBE. There's no guarantee this comp becomes S tier in patch 14.7 but there is potential, this is why it's marked as a "bonus" comp.
