Kayle
Returning in patch 4.5, Kayle remains one of the best team-carrying champions in Teamfight Tactics. All gamers need to do is position Kayle correctly and provide her with the Righteous Cannon. The Blade Master/Divine trait gives Kayle comprehensive attack and defense capabilities. Additionally, she is regarded as the “nemesis” of defensive items due to her overwhelming mixed damage output.

Ornn
The demigod from Freljord comes to patch 4.5 and quickly earns a lot of trust from players, especially in ranks from Platinum and above. Almost every top team composition features at least a 1-star Ornn, as his equipment forging ability is incredibly powerful, providing everything that basic items cannot.

However, Ornn is only truly effective when your team composition is sufficiently “tanky” and you have already established your playstyle (meaning not making too many changes). Therefore, try to find Ornn and upgrade him to 2 stars to quickly complete equipment for all team members in the late game, which will greatly assist your climb to the top.
Sett
Although he has been around since season 4, Sett has not lost his position and is even regarded as a hot champion with incredibly high game-changing potential in patch 4.5. Especially, if you roll an Ace Brawler early, Sett will be a key piece.

Provide him with one defensive item, and the rest can be mana or damage items (preferably mana), and then watch Sett demolish the battlefield.
Xayah
The Forest God composition, with its comprehensive attack and defense capabilities, is emerging as a highly favored meta. This composition is also considered perfect as it has both magic power and physical damage.
With the addition of shields from the Guardian trait of Xayah – Rakan, the Forest God trait can survive longer to stack armor/magic resistance. Equipping Xayah does not require much, with the most crucial item being the Justice Punch. However, the damage range of the Rising Storm is quite short, so you need a solid front line, as Xayah cannot stand in the usual position of carry champions in Teamfight Tactics (the back line) and must be near the front line, making her more susceptible to damage from opponents.

Samira
There is no need to elaborate too much on Samira’s dominance. Whether in League of Legends or TFT, she possesses immense damage output and a decent tankiness, making her difficult to burst down quickly. As a Risk-Taker champion, Samira also has a 100% evasion rate when using her abilities.

Because her strength lies in being a Risk-Taker, Samira can fit into any composition that needs more damage. Her core items include Giant Slayer, Justice Punch, and Guardian Angel.
