his cutie mark is his d-wheel/duel runner/card game bike, because from what i’m aware he seems to be pretty invested in building and customising it and just in general being a really good motorbike mechanic
not to insult his duelling skills in the slightest but it breaks up the monotony of card-related cutie marks
also i made a scribble of the mark on his back which is not a good scribble at all but do i look sorry to you
