To make it easier for yourself to rank up in Teamfight Tactics, you can follow the gameplay of the top streamers in the world. These streamers have a considerable understanding of the meta, popular team compositions, and even detailed knowledge of each champion.
Here are the streamers worth watching:
Keane

Dubbed the “Faker of Teamfight Tactics,” Keane is one of the most highly regarded streamers in the community. By watching Keane, you can learn how to arrange and utilize team compositions in the most effective way. Additionally, Keane’s adaptability in critical 1v1 situations (with only 2 players remaining) brings many surprises to his viewers during his streams.
Hafu

Once famous in the community for reaching rank 1 on the PBE server, this showcases her excellent adaptability in the “luck-based chess” mode. If you want to watch a relatively “chill” streamer who adapts well to new metas, Hafu is a great choice for you.
Deisik

As a player with a rank 1 Challenger account in multiple servers worldwide, his skills are unquestionable. He even offers tutoring for Teamfight Tactics at $30 per match, highlighting his confidence in the game. By watching his streams, you’ll learn a lot about team composition, card rotation, and item acquisition. However, a significant downside is that this streamer does not interact much with viewers, resulting in fewer followers.
k3soju

As a North American Challenger streamer, k3soju is also well-versed in Teamfight Tactics like many other names on this list. However, unlike the others, k3soju is quite lively and interacts a lot with viewers, making him quite popular in the community. If you want a somewhat “youthful” streamer, he will be a suitable choice for you.
Scarra

A player who may not possess the high skills of the aforementioned streamers, many viewers jokingly refer to him as the… gatekeeper of the Grandmaster and Master ranks in Teamfight Tactics. Additionally, this streamer has a slightly… slow demeanor but adapts quickly to the meta, so you can still grasp the meta by following this streamer.
Shaunz

He is one of the chillest streamers in the Teamfight Tactics community worldwide, as even when he turns on “tryhard” mode, he still interacts very enthusiastically with viewers. Using his knowledge of Teamfight Tactics, this streamer often holds roundtable discussions analyzing the strengths and weaknesses of each trait when new patch information is available.
Mortdog

Not as skilled or quick as the names above, Mortdog is still a highly entertaining streamer in the Teamfight Tactics community. The reason is that Mortdog is the… Lead Designer of Teamfight Tactics at Riot Games. Therefore, when playing Teamfight Tactics, this streamer always knows the strengths and weaknesses of the hottest meta compositions (simply because he is the one who decides to buff or nerf them). Additionally, as a designer of Teamfight Tactics himself, you can learn a lot about game mechanics by watching Mortdog’s streams.
