Even though Magnus only has 1 win and 1 loss, totalling 2 matches, he should still be considered a newbie right? Yet his reaction to hearing that our giant friend is a new combatant feels like it's from someone who's at least done 10 matches? Kinda weird imo, especially considering one of his matches was a loss so he should be loss confident. I wonder whats up.
