Caitlyn
Essentially, the Legend Caitlyn will help players in Teamfight Tactics acquire powerful Augments early in the game. The most notable is the Magical Two, which provides 2-star champions early on to help players secure winning streaks. This effect is incredibly strong in the early game when the stat difference between 1-star and 2-star champions is significant.

Moreover, the Augments provided by the Legend Caitlyn in the later stages enhance power towards the end of the game. Therefore, players can easily “pivot” according to the champions they have acquired.
Ezreal
Items have long been an incredibly important part of Teamfight Tactics. Thus, owning multiple items will provide players with more options for using carries and tank champions. The Legend Ezreal will supply a massive amount of items to players thanks to his Augments.

Furthermore, the Legend Ezreal also possesses an Augment that grants health to champions based on the number of items owned. This will greatly enhance the durability of the player’s team compared to usual. Therefore, the Legend Ezreal promises to be very suitable for newcomers to Season 9.
Ornn
Similar to Ezreal in providing items, the Legend Ornn brings his own special items. It is important to note that in Season 9, Riot has added 4 extremely powerful items from Ornn that support various types of team compositions. Therefore, Ornn is also a very strong Legend in terms of providing additional resources for players.

The only weakness of the Legend Ornn is that he does not provide Augments that enhance power based on items. However, since Ornn’s items are already stronger than standard items, this weakness doesn’t carry much significance.
Conclusion
With simple, easy-to-understand effects and good compatibility with various types of team compositions, the Legends Caitlyn, Ezreal, and Ornn are very friendly for newcomers to Season 9. Players should utilize these Legends to better understand Teamfight Tactics Season 9 with ease.
