>>50311063>magnet pull is good on magnezone because smogon says so.Magnet Pull on Magnezone is good because it allows Magnezone to trap and kill opposing Steel-types. Steel-types get in the way of a lot of types, like Fairy or Psychic. If Magnezone removes the opposing Steel-types, the Magnezone user now has free reign to set up and sweep with a Pokemon that might otherwise be stopped cold by Ferrothorn or Skarmory or Scizor or etc
HP ground is unviable on Blissey because Blissey has loads of other moves competing for that moveslot. Teleport, heal bell, seismic toss, thunder wave, toxic, wish, stealth rock, soft-boiled, and even counter are all more relevant moves that compete with that one move used to potentially 4hko Magnezone and nothing else (0 SpA Blissey Hidden Power Ground vs. 252 HP / 136+ SpD Heatran: 108-128 (27.9 - 33.1%) -- 75.9% chance to 4HKO after Leftovers recovery)
