This is a rather unique Steelix set that utilizes Torment in conjunction with Substitute to halt the enemy's attacks. By doing this, Steelix can stall the foe with Toxic or attack freely with Earthquake and Gyro Ball.

With Fire- and Water-types rising in dominance, Steelix's role as a Normal-type resister is constantly put into question. This set runs type-resist Berries that help mitigate its inherent weaknesses by taking advantage of the two assets that Registeel doesn't have: a good Attack stat, and STAB Earthquake.

Steelix has fallen a long way from the titanic status it once had back in GSC, but that doesn't make it a bad Pokemon by any means. Its amazing physical defense and 11 resistances, including immunities to Poison and Electric, make Steelix a reliable user of Stealth Rock in UU.

The purpose of this set is to lure in some of Steelix's usual counters, bulky Waters such as Milotic and Slowbro or Fire-types like Houndoom, and then use Explosion or Earthquake to clear the path for a sweeper, such as Dragon Dance Feraligatr or Swords Dance Venusaur, who are normally troubled by them.

Naturally, you'll want to start Steelix's sweep later in the match, when all Fire-, Water-, and Grass-types on the opposing team have been taken care of. Gyro Ball is the main attack this time, as the synergy between it and Curse comes naturally.
