Ledian's usable for setting up screens and delivering elemental punches.
Cleffa can actually cope early on, when everything has lousy stats, by inflicting status and taking advantage of STAB for offense. It should be evolved ASAP, however. Its durability will fall off miserably otherwise.
Swinub was pretty good - started slow, but Powder Snow made it a decent Pokemon, and Blizzard turned it into a glass cannon that scored several crucial OHKOs. I'm not sure why it was deemed Cleffa-tier.
Pineco is geared for one purpose: surviving just long enough to Selfdestruct or Explode. The ability to delete my opponent's strongest Pokemon was pretty much why I could get away with avoiding overgrinding until I hit a hard wall with the Elite Four.
Unown should not be used for any reason except gimmick runs. Of all the Pokemon to nominate for "not actually usable ingame", I would put this one at the top.
That was fun. Would do it again.
