Miltank has a new ability, "Scrappy". It allows it to hit Ghosts with Normal & Fighting attacks. Is it normal damage, or super effective or so?
I would assume it works the same way Foresight and Odor Slueth do: the target's Ghost-type immunity is simply ignored. This means, for example, that a Fighting-type attack will deal half damage to a Haunter but double damage to a Sableye.
