>>50566310The only Steel-types that truly did the job well have a second typing that takes care of the coverage move.
Taking Gen 5 Salamence(ran earthquake) as an example:
Skarmory- immune to ground
Ferrothorn- Grass makes coverage move neutral.
Heatran- only a good switchin with an intact Air Balloon unless you are certain the Outrage is coming.
Scarf sets occasionally also ran Fire Blast, which means Ferrothorn and Skarmory weren't actual counters to that one.
The only reason it doesn't run Fire Blast on the Dragon dance set is because these guys just get trapped by Magnezone anyway, so no point in wasting the moveslot.
