Cosmog is worse than Magikarp. Let me prove it
Magikarp: Has a movepool of Splash, Tackle, Flail, and Bounce. Ability Swift swim and Rattled. Has 2 weaknesses, Grass and Electric.
Cosmog: Movepool of Splash, and Teleport. Ability of Unaware. 3 weaknesses, Dark, Ghost and Bug. And it evolves to legendaries. I think it was to taunt Magikarp. Congratulations, Lillie and Sun and Moon, You ruined legends!
