Ground and Ghost moves don't affect Swellow at all — that's the advantage of Normal/Flying typing. It comfortably outruns most offensive threats. Comfortably outruns most offensive threats. Known as the Swallow Pokemon.
The stat budget goes to damage. Speed and Attack carry the offense, Sp. Def doesn't even come close. A Swallow Pokemon on a 1.06M XP medium-slow curve, worth 2 Speed EVs per KO.
If its two tail feathers are standing at attention, it is proof of good health. It soars elegantly in the sky.
Swellow Weakness
GoodElectric, Ice, and Rock-type moves hit Swellow for super-effective damage. The upside? Ground and Ghost-type moves can't touch it at all. At base 125 Speed, Swellow outspeeds most threats and doesn't need to tank what it can outrun.
