Some characters, especially the older they get, won't be meta or game breaking because of power creep. Sygna Suit Steven & Deoxys is a Poké Fair while Steven (Anniversary 2021) & Rayquaza is a Master Fair, yet Deoxys completely outshined it. Rayquaza has some unique utility by now being able to create a Flying Zone, and a fully invested one actually has some use, but don't go expecting it to ever be comparable to Arc Suit Cynthia & Garchomp.

I have SS Morty at level 200, maximum superawakening, EX role, 6EX, 70/60 grid, you name it, but the fact of the matter is that even if his bulk is only slightly below AS Steven & Mega Metagross, he cannot buff Attack or Sp. Atk above a +2 no matter how you grid him. Instead, he's built around having ridiculous sun support.
>Sunny Day
>Sunny Day: MP Refresh 3
>Sunny Day: Team Body-Bracing Affliction 2 - raises party Defense by +2
>Sunny Day: Team Mind-Bracing Affliction 2 - raises party Sp. Def by +2
>Sunny Day: Team Hit and Heal - applies gradual healing to the party
>Group Afflictor's Advantage 1 - raises the party's main stats by +1 the first time a status move (Sunny Day) is used
>Believe! - also raises crit by +1 during sun
>Believe!: MP Refresh 3
>Team Sunbathe 9 - Restores the HP of all allied sync pairs when the user uses a move while the weather is sunny
>A Golden Future - Extends sunny, raises users phys/special moves by +1 after using a status move (Sunny Day)
>EX role - Field (makes the weather sunny after sync)
>Team Gimme Five 1 - raises party's main stats by +1 after first sync
>Sunny Disposition - user's stats can't be lowered in the sun
>Speeding Sun 2 - move gauge charges faster in sun
>Sunbathe 9 - restores user's HP when using a move in sun

It's just unfortunate he can't be gridded to hold them all at once. If grids could be even more open, so many characters would improve.
