Grass/Steel strategy: Poison immunity with a 4× Fire emergency
Grass/Steel and Steel/Grass are the same defensive pairing; this page uses grass-steel as the canonical URL. Grass/Steel is a high-compression defensive pairing that blocks Poison and resists many common attacking types. Representative Pokémon include Ferroseed, Ferrothorn, Kartana. The standard type chart gives this combination 4× weak to Fire and 2× weak to Fighting. It is immune to Poison. Its main defensive value comes from ¼× resists Grass; ½× resists Normal, Water, Electric, Psychic, Rock, Dragon, Steel, Fairy, but stats, ability, item, and format still decide whether a real Pokémon can use those entries repeatedly.
Offensive plan
Grass STAB pressures Water, Ground, and Rock targets, while Steel STAB threatens Fairy, Ice, and Rock targets. Fire is the severe 4× weakness and Fighting also hits for 2×, so the typing needs careful matchup control. It is strongest when its many resistances create utility turns rather than when it is forced into Fire coverage.
Counterplay and defensive risks
To counter Grass/Steel, start with the chart pressure: Fire, Fighting. If a 4× weakness is listed, preserve that attack type before revealing it; if there is no 4× weakness, repeated 2× pressure and hazard chip usually matter more than a single surprise hit. Scout for abilities, Terastallization, weather, recovery, and pivot moves before assuming the visible multiplier ends the exchange.
Team-building advice
Grass/Steel needs Fire protection and a Fighting plan. Water, Dragon, Fire-resistant, Ghost, and Flying partners can help, while Grass/Steel handles Water, Electric, Grass, Rock, Fairy, and Poison-related pressure. Use the Team Calculator to check whether the rest of the six stacks the same Fire, Fighting problem, then compare the full defensive chart before choosing moves or teammates.
