What about him keeps his popularity so solid?
He has been popular for years since his reveal but was not really shilled.
Seemingly out of no where after being treated like a normal mon for so long they acknowledged him

>Mega
>Playable in pokken
>Obtainable in basically every single game
>Trade requirement destroyed in gen 8
>G-maxed
>Nerfed (bad attention but attention none the less)
>A main spot on Ash's team
>Bounces back to OU despite the nerf

What keeps him so relevant and popular despite not even being the highest preforming or most popular ghost type?
