What it does
I'm not aware of "Hyperfrag Round" as an actual Magic: The Gathering keyword or ability. It doesn't correspond to any official mechanic, keyword action, or ability word that I can verify exists in the game.
It's possible this is from a custom/homebrew card, a joke set, a misremembered name, or a term from a different game entirely. If you encountered it on a real card, double-check the exact wording—it may be a flavor name for an ability rather than a keyword, or the card might be from an unofficial source.
If you can share the full card text or where you saw it, I'm happy to help interpret how it would work in Commander. I'd rather tell you I don't recognize it than invent rules that could mislead your gameplay.
