Ferroseed Weakness

Fire and Fighting moves hit Ferroseed for super-effective damage. Fire hits land at 4x, so they're the biggest threat. The upside? Poison-type moves can't touch it at all. 9 resistances give it solid defensive coverage on top of that. With 44 HP and balanced defenses, Ferroseed can afford to eat a neutral hit or two.
