Scotland coach Andy Robinson has signalled his side's intent to run the ball at Argentina on Sunday with his selection of Ruaridh Jackson at fly-half.
While many might have expected Dan Parks to retain the number 10 jersey having enjoyed success against the Pumas in the past, Robinson said Jackson's ability to take on the line and feed his backs had earned him the selection for the crucial Pool B contest in Wellington.
"He has a very good ability to go to the line and challenge defences," said Robinson.
"We believe going into this game it's important for us to play with ball in hand as well as have the balanced game of kicking.
"We want to bring our dangerous runners like Max Evans, Sean Lamont, Chris Paterson and Graeme Morrison into the game."
Jackson's selection and the dropping of captain Alastair Kellock were the main talking points following the announcement of the team which shows five changes to the one that scraped past Georgia 15-6 in Invercargill.
Scrum-half Rory Lawson will captain the side in Kellock's absence.
The return of Paterson at full-back is the only other change in the backline.
Jim Hamilton and Richie Gray come into the second row in place of Kellock and Nathan Hines, while prop Geoff Cross replaces Euan Murray, who does not play rugby on a Sunday for religious reasons.
First-choice open-side flanker John Barclay also returns, taking over from Ross Rennie.
Robinson admitted the decision to drop Kellock had been a tough one but he felt that Hamilton would provide the power in the scrum and Gray the mobility to counter a strong Pumas pack.
"Euan is our best scrummager and Euan is not playing in this game so putting some real weight behind Geoff Cross on that right hand side that's what Jim Hamilton gives us," explained Robinson.
"Jim has led the line-out well in the game he played in [against Georgia] but also in the Ireland match in the warm-ups.
"Then it's putting together a second row that could work with Jim that could give us the ability to play quickly.
"I believe Richie Gray, who is an outstanding second-row forward, has that ability to work for us in open play with his athleticism."
Scotland and Argentina have faced each other five times since the last World Cup, with the Scots winning three of those contests including a historic series win in South America last year.
With Argentina already losing to England, the Pumas know that they need victory on Sunday to have any chance of reaching the last eight.
