Gen 6 Steel Type Shift: New Defensive Weaknesses

In Generation 6, the Steel type's defensive strengths were notably altered when it lost its resistances to both Dark and Ghost types. This game mechanic change effectively gave Steel two new effective weaknesses where none existed before, fundamentally impacting its viability and matchups. For competitive players, this means that common threats utilizing Dark and Ghost-type moves, previously walled by Steel, now pose a significant offensive threat. This shift demands careful consideration for Steel-types like Metagross, which now face different calculations against these move types.
