Oscar "AZUWU" Bell began his Counter-Strike career in March 2021. He started out in lesser-known teams, frequently switching rosters. Between March 2021 and July 2022, he changed teams around ten times but failed to achieve any significant results.
Despite this, in the summer of 2022, he received an offer from 1PIN and signed a full contract. This gave Oscar more confidence, allowing him to showcase a higher level of play. With the team, he secured silver medals at ESEA Cash Cup: Europe - Summer 2022 #2 and #4, as well as championship titles at SCL Season 6: Challenger Division and Kayzr League Fall 2022.
Following these achievements, he once again moved between smaller teams without notable success, only managing to win a few minor tournaments. However, he continued to display solid individual performances, which led to him joining Coalesce in January 2023. With the team, he immediately placed 1st-4th at CCT Season 1 West Europe Series #1: Closed Qualifier, and later won EPIC.LAN 38.
In July 2023, Oscar signed with Endpoint, further expanding his list of achievements. With the team, he became champion at ESL Premiership Autumn 2023: Closed Qualifier #2, RES Western European Masters: Fall 2023 - British & Irish Qualifier, Monsters Reloaded 2023: British Qualifier, and RES Western European Masters: Spring 2024 - British & Irish Qualifier. Additionally, he secured silver medals at ESL Premiership Autumn 2023: Closed Qualifier #1 and RES European Masters Fall 2024: British & Irish Qualifier, while also finishing 1st-2nd at Monsters Reloaded 2024: British Qualifier and 3rd-4th at ESL Premiership Spring 2023.
