Meta Snapshot Summary
NEW SET 3 Meta Snapshot. Every composition is new. If you do not see a composition on this Tier List, it either is not strong or not popular enough to include. I am sure as the weeks go by, there will be many many more compositions! Rebels are by far the best, followed by Blasters + Brawlers and Cybernetics. Tons of experimentation still as people have only had 3 days on the new set!
S: Rebels
A: Blaster + Brawler, Protector Infiltrators, Cybernetic
B: Mech Pilot Infiltrator
C: Sorcerors

Item Quadrant
The closer to the Top Right, the better and more versatile the item is. Avoid items on Bottom Left if possible.
Strength (y-axis) is based on how effective an item is in the situations where it is most used. Items that are strong at all stages of the game are listed higher.
Versatility (x-axis) is based on both the number of Compositions an item fits in and Champions an item is used on. Versatility is also how often you could build an item.

TFT Compositions Tier List
Methodology
I scout the Top 10 players in all major regions and analyze what they play and how they play each composition. Tiers are determined by what I think will get you the highest average rank. This means that while one composition might be super strong late game, it may be difficult to acquire, so it may not be S-Tier. For example, it is difficult to win with certain compositions, but extremely easy to Top 4. Rankings within a tier are very close together. Always try to play with what makes sense for every game, and adapt to your lobbies with proper tech choices.
Difficulty, Item Dependency, and Variance are listed. Difficulty is how hard the composition is to play. Difficulty does not factor into the strength or viability of the composition but serves as a factor for new players. Item dependency is how important specific items are to the composition. Variance is the approximate placement range of the composition. For example, a consistent Top 4 composition has low variance. A composition that either places 1st or 8th has a high variance. If I mention that a composition is Forcible, it means that you can play this comp every game.
Tier placement assumes strong play. Refer to Difficulty metric before attempting to play.
S-Tier: Highly Flexible or Very Strong
Rebels

Rebels are very consistent and strong. Aurelion Sol with Morello is very strong. Aurelion with Demolitionist is also very good when combined with Ziggs.
Difficulty:
Item Dependency: High
Variance: High
Rebels utilize their shield and damage buff to strengthen each other. It is reliant on having Aurelion Sol and strong items. Add in Mystics if you are against magic damage.
A-Tier: Solid Team Comps. Weaker, less flexible, requires more luck than S-Tier
Blaster Brawler

Difficulty: Medium
Item Dependency: Medium
Variance:
Keep Blitzcrank next to Jinx to let her get a quick kill. Rebel spatula is useful to get to 3 Rebel.
Hyperroll Protectors

Difficulty: High
Item Dependency: Medium
Variance: Low
Base composition is 4 Protectors and Kaisa and Shaco, the rest of the slots are up to you. You want 3* of all your protectors along with Kaisa and Shaco.
Cybernetic

Difficulty: Medium
Item Dependency: Low
Variance:
Cybernetics benefit from having at least 1 item, so it’s great to diversify your team with this build. Lucian is a great early game carry and then you can transition into Irelia and Ekko.
B-Tier: Playable, but not Preferred. Comps could also be untested.
Mech Pilot Infiltrator

Difficulty: Low
Item Dependency: Medium
Variance: Low
This is a great top 4 build. Shaco with BT and then any BF item and a defensive item is very strong if no one has Red Buff or Morellos
C-Tier and Below: These are compositions that are weak, but if they are given to you, you might be forced to play them. I may also use this section as an archive of out of meta compositions for reference.
Sorcerors
Difficulty:
Item Dependency:
Variance:
There has not been success with Sorcerors yet, so I will leave this blank for now.
