What is a golf shamble?

From google: A "shamble" is a type of Golf tournament format in which a team of golfers selects the one best drive among them after teeing off, then all four play their own golf balls from that position into the hole. 2 Best balls of the team will count towards the TEAM SCORE. Generally, par 3s don’t scramble off the tee, par 4s do, and par 5s scramble first 2 shots of the hole.
