Ferrothorn

Ferrothorn has high defenses along with a fantastic defensive typing that grants it nine resistances and one immunity, allowing it to be one of the most capable walls in VGC. Ferrothorn's typing also gives it immunity to Spore and Sleep Powder and lets it take on Fairy-types. Ferrothorn's fairly high Attack stat allows it to hit with its powerful STAB moves, Gyro Ball and Power Whip, the latter having the capability to OHKO Rotom-W on the switch, though Ferrothorn does have to watch out for a burn. Ferrothorn's horrid Fire-type weakness is exploited by common threats such as Mega Charizard Y and Talonflame. Furthermore, Ferrothorn faces competition from Mega Mawile as a defensive Steel-type and from Amoonguss and Gourgeist as a bulky Grass-type.
