Pandya, Rahul and Pant - all 3 are world class players and vital to our chances in T20 side. So all of them will play.
Though Pant has not lit the world on fire in T20 stage yet, considering his potential I am sure he will do more in future. His highest score is already more than MS Dhoni's entire career with almost similar strike. Also his strike rate of 123 is not that bad...he will only improve from here. I mean our world no.1 T20 batsman Babar Azam also bats at a strike rate of 130. So a bit leeway can be given to Pant.
Also remember how before Australia tour you were going on and on about how Pant is a failure in test cricket and how Saha deserve to play above him. Had people followed your intelligence we would have never won the series there.
So sometimes you pick players on intution, potential and cricket acumen. Hence I said, every team in the world would pick Rishabh Pant on their T20 team (maybe except Eng).
Then again, you know all these very well too but just pretending
