Both Zeri and Nilah are experiencing remarkably low pick rates despite being the newest Marksmen from Riot Games.
In the realm of League of Legends (LoL), newly released champions often come with overwhelming strength, leading to high pick/ban rates. This is especially true for damage-dealing roles like Marksmen.

However, at the current moment, both new Marksmen introduced by Riot in 2022 have alarmingly low pick rates. According to U.gg statistics, Zeri currently holds a mere 1.1% pick rate, and Nilah sits at just 3.6%. These surprising numbers place both Nilah and Zeri among the least picked Marksmen in LoL.
For Zeri, the issue lies in the champion being nerfed multiple times by Riot Games throughout the 2022 season. This has left Zeri's damage output extremely weak, making it difficult to secure kills. Coupled with the fact that Tanks are proving too resilient with high health pools in the Early Season 2023, Zeri has almost no chance to shine. Consequently, Zeri boasts a 42.53% win rate according to statistics.

Nilah's situation differs slightly from Zeri's, as this champion still holds a stable power level. A 53% win rate is the clearest evidence of this. However, Nilah's playstyle doesn't quite align with the preferences of Marksmen players, leading to the community giving this character the cold shoulder.

Fundamentally, Nilah operates quite similarly to a Fighter in the Bottom Lane. Nilah's ultimate also requires players to dive into the enemy formation rather than maintaining a position like a traditional Marksman. Therefore, Nilah excels in the hands of players who understand this champion but is not favored by the majority of Marksman players.
Conclusion
In summary, Riot's two latest Marksmen are facing significant issues with their strength and playstyle, resulting in a lack of popularity among the gaming community. Perhaps Riot Games should boost Zeri's power slightly and reduce the difficulty of Nilah to garner more attention from League of Legends players.
