Koffing

It's not hard to see why Smogon praises Koffing. When taking a quick look at Koffing, you'll notice its exceptional Defense stat, resistance to the plethora of Fighting-type moves, and incredible ability in Levitate. Dig a little deeper and you'll find a good movepool filled with interesting attacking and supporting options. However, like most Pokemon, Koffing is not without its faults. Koffing's Special Attack stat is mediocre at best, which means that powerful attackers such as Chinchou and Magnemite can take advantage of it with ease. Additionally, Koffing's low Special Defense stat lets most special attackers 2HKO it. To make matters worse, Koffing doesn't have access to reliable recovery outside of Rest, giving it difficulty sticking around for very long. However, don't let these faults deter you; when played to its strengths, namely walling most physical attackers in Little Cup, Koffing can prove to be a valuable member of your team.
