BBC Sport has worked with data analysts CricViz to look at the strengths and weaknesses of each side.
Men’s team
Fire added Stephen Eskinazi, Tom Abell and Glenn Phillips to their batting line-up during the draft, securing three high-quality batters who should be able to provide runs in the middle order, an area where they’ve severely lacked production over the past couple of years.
The engine room should have the cushion of fast starts from Jonny Bairstow and Joe Clarke at the top as well as hitting depth provided by the likes of David Willey, Shaheen Afridi and Roelof van der Merwe.
The lack of a high quality left-hander is perhaps their only major concern, particularly limiting their ability to exploit lopsided boundaries should the opportunity arise.
The draft also saw Fire add plenty of quality with the ball. Left-armers Shaheen and Willey should trouble batters with new ball movement, and a high-pace combination of Pakistan’s Shaheen and compatriot Haris Rauf should see an improvement at the death.
Fire will be hoping their finger spinners, like left-armer van der Merwe and off-spinner Phillips, can make use of the square boundaries at Cardiff, although they could be hurt by the lack of a true frontline leg spinner who turns it both ways.
Women’s team
Fire picked Sophia Dunkley with the first pick during the draft back in March. The England opener had plenty of success opening the batting for Southern Brave but will have to adapt to the challenge of batting at Sophia Gardens.
Fellow England opener Tammy Beaumont joins Dunkley, Hayley Matthews and Laura Harris to provide a power packed batting line-up that should perform better after struggling last year.
The fastest bowler in the world and two-time Hundred winner Shabnim Ismail moves across from Oval Invincibles to bring some heat to the Fire bowling.
Left-arm spinner Alex Hartley and off-spinner Hayley Matthews are both capable of bowling at the top of the innings and at the death and bring added flexibility to the Fire attack.
The likes of Freya Davies, Georgia Elwiss and Emily Windsor all provide valuable skills alongside the Fire’s big names.
