Sciver-Brunt said all will be revealed at the toss at Edgbaston on Friday, but the England captain did note that all members of her squad would likely get the chance to show their wares during the 12-team tournament.
"We have a squad of 15 players, all of whom could be part of our XI," Sciver-Brunt noted on Thursday at the pre-match press conference.
"Selecting that final XI is hard and there'll be some disappointed people because everybody so far in the summer has put their hand up with different performances at different times.
"We know that we'll need to call upon every one of those 15 people during this tournament.
And I suppose that makes for some tough conversations and I'm sure some disappointed people."
But where that leaves all-rounders Freya Kemp and Dani Gibson remains unanswered, while there is also plenty to ponder for the England captain at the top of their batting order with Danni Wyatt-Hodge, Amy Jones, Alice Capsey and Sophia Dunkley all jostling for positions.
