The Bulldogs' assistant captain brings a wealth of World Junior experience to the Czechia lineup with full appearances in 2020 and 2021.
He also captained his countrymen last December prior to the cancellation of the tournament due to a series of positive COVID-19 tests.
Mysak, who will serve as captain again, was a second-round selection (48th overall) in the 2020 NHL Draft.
