Offense: Hazard setters: (Suicide Lead) For be one of the a few suicide lead on the RU tier that can put Stealth Rock and layer of Spikes, have a good bulk paired with a nice ability: Study, capable to put another layer of spikes thanks to Custap Berry that allows to hit first when is very down (25%~). Also, can run another interesting items such Red Card, Lum Berry or another more bulky oriented lead with leftovers. Rock Blast is a staple on Crustle to get a good matchup lead against stuff like Accelgor or Aerodactyl. To finish, X-Scissor or Earthquake are another cool offensive options, mention too Shell Smash but you should to run only one hazard in this case. Hail: (Utility / Spinbloker) Is ghost so have a niche keeping your hazards on your Hail team, preventing to spin Cryogonal and Hitmonchan (w/o SE). Because Flash Fire can check pretty well dangerous threats for Hail teams such Sunny Day Moltres, Sunny Day Entei, CB Entei, Escavalier, Emboar and some others threats like Lilligant Hp fire. Flamethrower and Shadow Ball are both moves necessary in Lampent, while the last options should be Pain Split or Rest, and another status move like WoWisp.
