The Scorchers earned the right to host The Final after finishing at the top of the WBBL table after the regular season, while the Strikers won their two finals matches on Wednesday and Thursday to reach the decider.
Devine said Adelaide will be competitive, but Perth has the tools throughout the order to lift the trophy.
“The Strikers have got threats throughout, but we know as well, we've got to back our strengths,” she said.
“We also have to follow our processes, which I think has been really important for us all week."
Batter Chloe Piparo agreed, saying the team has the belief they can get the job done, no matter the circumstance.
“In the past I think the Scorchers have relied heavily on our top order,” she said.
“For the middle order to stand up on both Saturday and Sunday was ideal, we know we can win the game from any position now.”
Saturday’s Final will be the first time the Scorchers have competed for the title since WBBL|03, with Heather Graham and Piepa Cleary the only ones in the current squad to play in that game.
However, the Scorchers have a plethora of finals experience, with Devine and Beth Mooney competing for the Strikers and the Heat respectively in the WBBL|05 Final, while Alana King played for the Stars in last year’s decider.
The New Zealand international said it was important to stay grounded despite the big occasion.
“I think you can get sucked in a little bit to the hype of finals and everything, and we certainly acknowledged that is a bit different for us,” Devine said.
“At the end of the day it's another game of cricket, so we need to prepare as we have done for the last 14 games of the season.”
Devine had full confidence the side would be competitive in either setting a target or chasing a total in The Final.
She said her role as captain was to channel the emotion of her teammates into playing their best cricket.
“I think it's pretty clear that it's going to be a big game and there's going to be a few emotions rolling around,” Devine said.
“I think that it’s about acknowledging and accepting that it's okay to be nervous, excited, whatever you're going to feel and, and using it to your strength.”
The Perth Scorchers haven’t played at Optus Stadium since 2018, but allrounder Heather Graham said the conditions won’t be unfamiliar.
“It's just a little bit of a bigger ground but it's pretty similar to the WACA Ground and how it plays,” she said.
“The pace and bounce of the wicket, and the speed of the outfield is pretty similar as well.”
Devine said the home crowd would have a role to play, and praised the Scorchers fans for their support.
“Perth people love this sport and to know that they're going to be backing us all the way is something that I'm certainly really excited about,” she said.
“It'll be well and truly the biggest crowd I've ever played in front of, so I’m certainly really looking forward to it and it just adds to the whole spectacle for us.”
The Final against the Adelaide Strikers gets underway at 4:10pmWST, where the Scorchers will be looking to take home their maiden WBBL championship.
