The panel in the centre of the controller, between the two players.

Reset Match
Section titled “Reset Match”
Reset Match asks for confirmation, then:
Cleared
- both hands
- all annotations on both sides
- life totals, back to 20
Kept
- wins
- decklists
- player names
That split is deliberate: it is the “next game of the same match” button. Bump the winner’s wins first, then reset, and the scoreboard carries the match score into game two.
