The information you provided about the ICC World Test Championship and the potential changes in the Indian playing XI is accurate. India will indeed face Australia in the WTC final starting on June 7, 2023, in London. The Indian team will be missing some key players like KL Rahul, Rishabh Pant, and Jasprit Bumrah due to various injuries.

To replace KL Rahul, the Board of Control for Cricket in India (BCCI) has chosen wicketkeeper-batsman Ishan Kishan, who is yet to make his Test debut. Former Australian captain Ricky Ponting has expressed his opinion that Ishan Kishan could bring an X-factor to the team and should be included in the playing XI for the crucial WTC final.

Ponting also suggested that all-rounder Hardik Pandya could be valuable for India in a one-off Test match like the WTC final. Pandya has been performing well in white-ball cricket and has been bowling consistently in the Indian Premier League (IPL). However, Pandya himself had previously ruled himself out of contention for Test cricket until he feels he has earned his spot by going through the grind and performing consistently in the longer format.

It remains to be seen how the Indian team management and selectors will approach the selection of the playing XI for the WTC final and whether they will consider the inclusion of Ishan Kishan and/or Hardik Pandya based on the available options and the team’s requirements.
