He said it was a different feeling going against his former team.
"There are a lot of friends you have on a team, and you went through blood, sweat, and tears together, but you have to put that aside and fight for the jersey you are playing for," he said.
Buchanan is among 13 newcomers for the Wings, who revamped their roster following a 7-9 season.
Another newcomer, Jordan Hall, acquired from the reigning NLL champion Rochester Knighthawks, had a goal and six assists for the Wings.
There are still key Wings holdovers, including second-year forward Kevin Crowley, who scored four goals and was impressed with Buchanan's debut.
"He is one of the quickest guys I know," said Crowley, who had 36 goals last year. "His ability to go one on one opens up so much space for others."
Rookie Ethan Farrell scored the first goal of the season to give the Wings a lead with 3 minutes, 43 seconds gone in the first quarter.
The Wings took a 3-2 lead on a power-play goal by Crowley with 52 seconds left in the first period and never trailed after that.
Crowley's goal was the first of four consecutive power-play scores for the Wings.
The Wings led by 8-4 at halftime, and Buchanan helped set the tone with two goals and three assists.
Goalie Brandon Miller had a strong game for the Wings, making 43 saves.
