Jigglypuff is ranked 36th out of 41 on the official tier list, in the midst of the D tier. This is an improvement over its Brawl placement, where it was 36th out of 38, but still a very significant drop from its Melee placement of 5th out of 26.
Despite retaining all of its most favorable attributes from Melee and gaining minor new ones, Jigglypuff's tournament success relative to the cast is more reminiscent of its significantly less viable Brawl appearance as a result of many characters gaining new options to combat Jigglypuff's. Despite this, Jigglypuff is still a capable character in competitive play.
Changes from Melee to PM
Jigglypuff has remained relatively unchanged from Melee to Project M, although it has gained a few additional options from Brawl-based mechanics.
Up to date as of version 3.6.
In competitive play
Jigglypuff now gets back its yellow crown costume from Melee as another palette swap. It additionally has a new costume that gives it a more opaque color and fairy wings, which emit sparkles when moving in midair; this heavily references the fact that Jigglypuff has become part Fairy (type) in recent Pokémon games (more specifically the Generation VI games), which is a newly-introduced elemental type. PMDT had confirmed on their subreddit that Jigglypuff would have an additional alternate costume based off its headband costume in Melee in a future version of Project M. While it never made it into the mod officially, it was later released on the Brawl Vault.
