The team finished on top of the table with 6 wins in 8 matches and directly qualified for the final.
Afghanistan star Rashid Khan will miss the final as he has traveled to the UAE for a tri-series ahead of the Asia Cup.
Australian leg-spinner Adam Zampa will replace Rashid Khan for the final and fly in from Australia.
Zampa has a strong record with Oval Invincibles, taking 19 wickets in 9 matches last season, and 6 wickets in 3 games in 2023.
Zampa will travel nearly 34,000 km round trip (Australia to England and back) just to bowl in the final, with flights taking over 20 hours each way.
Before leaving, Rashid took 12 wickets in 6 matches, playing a crucial role in helping Oval secure victories.
Oval Invincibles await their opponent, which will be decided on August 30 between Trent Rockets and Northern Superchargers in the Eliminator.
