Depends on the available card pool and other considerations, decks don't exist in a vacuum, they live and die in a metagame. You wouldn't usually play it, no, but it can occasionally be useful. More often than not you have better options. My favorite example is how Infect in Mirrodin/M12/Innistrad Standard used to sideboard Melira. Its only purpose was to kill an opposing Melira (this was with the old legend rule). Would you normally play that card? No. Would you situationally play that card? Yes. ¯\_(ツ)_/¯
