Buddhette, use three Rock Slides on Cinders. Magic Coat anything used against you that is Magic Coatable.

Del, use Giga Drain on Snappy until he falls. After that, use any actions remaining to attack Spicy with Blizzard and then Cinders with Hydro Pump (in that order). Magic Coat anything used against you that is Magic Coatable.

Love, use Protect + Megahorn on Spicy. If you're still alive after that, use another Megahorn on her.
