>>46834873The problem being that Glowking has Future Sight and Toxic Immunity on top of good coverage. Future Sight is the main reason it'd entirely outclass Goodra, since it can force progress quite easily, while Goodra is only useful as a pivot.
It'd be outclassed in OU where all the special attacking Fairies are, and fall to UU where it'll get destroyed by Tapu Bulu, Salamence, Mamoswine, Komo-o, Buzzwole, Conkeldurr, Aegislash, and all the other physical attacking monsters. Plus, as a special wall, it's outclassed by Chansey, since Chansey is weaker on the physical side, but more resilient to special attacks, is immune to status, and has teleport for maximum pivoting.
