Groundbreaker puts 6 power of trample into play for three mana — one of the most efficient green threats ever printed — then leaves at end of turn. Under Mr. Orfeo, the Boulder, that drawback evaporates: the damage is dealt before the sacrifice matters, making this a clean three-mana, six-damage spell stapled to a body.

Mr. Orfeo, the Boulder
Mr. Orfeo, the Boulder doubles Groundbreaker's combat damage, turning a six-power trampler into a twelve-damage swing for three mana — the end-of-turn sacrifice is irrelevant when the game is already over.

In Commander, Groundbreaker fills a specific role: high-pressure, low-cost damage in decks that want to close games fast rather than grind. Legacy and Vintage see it occasionally in green stompy shells as a Rancor-adjacent threat — cheap, immediate, and threatening enough to demand an answer. Modern offers it the same home in aggressive green creature builds, though Collected Company-style value decks typically want permanents that stick. Groundbreaker's Pioneer and Standard illegality is irrelevant to where it actually sees play — the card lives in formats where three mana for 6 power is a legitimate offer.
