Kecleon

A huge Special Defense stat, decent Attack, and a massive movepool give lots of reason to use Kecleon. With just Protect and Leftovers, Kecleon has a lot of staying power, and on the offensive it can be pretty difficult to switch into. Unfortunately, the chameleon falls pretty short of being an "NU Snorlax." Color Change is a huge mixed bag of an ability, and while it works in Kecleon's favor sometimes, more often than not it gives the opponent a workaround to break it faster. Most of the special attackers in the tier carry moves that are super effective against their STAB move or vice versa, and Kecleon's low Defense means most physical attackers just blow right through it. In the end, Kecleon is great on support and forms one of the most potent defensive cores in the tier with Relicanth and Chimecho, but don't expect it to "one-man army" the opponent.
