Here's what I got on Wilson Björck

He's a center/left wing; 6'0 2006 baby; from Stockholm, Sweden
He played in Djurgårdens J20 where he achieved 67 points (28 goals and 39 assists) this past season. Which was the highest in the league, only being surpassed by his younger brother who is eligible for the 2026 draft. He then scored 9 points during the playoffs as well.
In terms of as a player, he's projected to be developing similar to other Swedish pros such as Elmer Söderblom and Pierre Engvall. Though most say he still has more to come as he did play in the Djurgårdens professional team for 10 games but didn't end up with any points to show for it.
He's quoted on having good motor, vision, and able to play defensively and in all 3 zones. A lot of his skill isn't the most stand-out but many believe with time he will even surpass other Swedish pro players.
As of right now, he won't be heading back to Sweden to play for Djurgårdens. As of the 25/26 season he'll be heading over to Colorado to play for Colorado College in the NCAA (Who signed him like 4 days ago)
Also I found this image

There's not really much on him online (at least in English) but this was what I was able to find.
