This sort of thing is the bread and butter of writer Tom Taylor, who once again partners up with Marguerite Bennett for this issue. Bennett's something of an unknown quantity here, but her previous work on Batgirl and Batman has proven her to be a writer of no mean skill. It's unclear just how the writing duties were split between them but the fact that one fails to detect any difference in the writing styles between scenes proves that the two writers play well together and that we all benefit from the partnership.
The same can be said of the artwork, which is handled by two separate teams of artists. One group handles the pages involving flashbacks to Huntress and Power Girl's pasts. The other handles the main action of the issue. Both teams do a fine job depicting the action and there's no glaring difference in the styles that might wreck a reader's focus.
