Scotland is taking on Argentina this weekend in the last test of the November test series.
They will want to bounce back after the loss last weekend against the Springboks.
Scotland coach Townsend has made nine changes to his starting lineup for the clash.
He decided to change three in the backline with Laidlaw to captain the side from nine.
Russel will move to inside centre with Hastings starting at the number ten jumper. Huw Jones will partner Russel in the midfield with Kinghorn starting on the wing.
In the forwards, Townsend have decided to change six which includes a new front-row in Dell, Brown and Berghan.
Gray will be joined by Toolis in the second row with Ritchie and Watson on the side of the scrum. Strauss will start the test at number eight.
Stuart McInally and WP Nel move to the bench and are joined by Glasgow Warriors prop Alex Allan
Townsend said: “While it was a great effort from the players to win in Argentina last summer, we are under no illusions as how different a prospect their team will be on Saturday.
“Under Mario Ledesma Argentina delivered some outstanding performances and they were hugely impressive in their victories over South Africa and Australia in the recent Rugby Championship. I’m sure that they will throw everything at us to end their international season on a high note.
“With four Test matches in succession, we’ve been conscious of rotating the squad to enable as many players as possible to be in the best physical condition for each contest.
“We are expecting those selected this weekend to bring energy and huge effort to the game and seize the opportunity to perform at their best level against a very good team. It will be another huge challenge, not only for our forward pack, but also for our defence – as Argentina play ambitious, skilful and effective attacking rugby.”
