Clefable a really underrated attacker?

I also have a perfect but the Clefable doesn't have DG. (I'm fairytale cursed as Wigglytuff lacks PR and Clefable lacks DG). Never use it as any role. Offensively its role can be better done by other mons from other types (e.g. Dragon by Dragon or Ice, Fighting by Psychic or Flying). Defensively tends to use Master tier trio and those which can hardly get candy (so when feeding berry there's chance to get candy).

EDIT: I misread the title. Clefable is a completely worthless attacker due to its low attack stat. It can't contribute meaningful DPS for soloing Machamp even at level 40 unless the weather is Cloudy.

Ok defender though, drop between two normal types and you have a discount Gardevoir.

Fairy type needs a fast move...

As mentioned, Clefable makes for a decent gym defender, but as an attacker, it's not really anything to write home about. Since it only has Fairy-typing, it lacks access to any STAB quick moves, and its attack and defense stats are pretty mediocre. It has a good amount of HP, but trails Gardevoir by 49pts in defense, which results in their overall bulk being quite similar. On top of that, Gardevoir is packing 59pts of extra attack, has better typing in some matchups, and access to the hard-hitting STAB confusion.

TL;DR: Gardevoir! All the Gardevoir! 😁

Not so keen on Clefable as an attacker, but as a defender, makes a lot of sense. Sitting between a Blissey and a Snorlax, the Machamp that takes those two down will get absolutely hammered by Zen Headbutt and Dazzling Gleam. Even Moonbeam does all right in that role.

Of course, a good gym attacker will know to switch out to any poison or steel pokemon to take down Clefairy, but if someone's being lazy, wham.
