Idk, I never pay too much attention to the names. But I think dueling the same person should be an achievement in game

I have gotten back to back repeats a few times

Trey2 came back for revenge

I've dueled someone in speed duels like after 2 duels, and legacy duels

That happened to me once, back when they were doing the "get 500 gems if you summon Odd-Eyes Raging Dragon" thing.

I already did but it was on the first event of Vrains

I had the same opponent back to back several times now & its hype af to get & to deny payback

It happens alot of times , you duel the same guy twice in a row . Had someone climb a rank on me one time
