>>27950534Wiggly's three abilities are Cute Charm, Competitive and Frisk.
Frisk and Cute Charm are worthless so one or both of those should be replaced, preferably Frisk as Cute Charm fits the line from a design standpoint.
Wigglytuff needs a better STAB than Dazzling Gleam and Hyper Voice to help with a lower Sp.Atk stat.
Giving Wigglytuff another good ability aside from competitive would help it out greatly as it can run a wider variety of sets.
Personally, I'd like to see Wigglytuff become more like Togekiss in that it suffers from having a massive movepool but can only have four moves.
