I should have seen this coming! Other than Mewtwo, who is the best competitively?
No; it's just UU; it's usable above there, though.
The OU/Uber Gen I Pokémon are Dragonite, Venusaur, Cloyster, Starmie, Alakazam, Ninetales, Jolteon, Tentacruel, Dugtrio, Gyarados, Gengar, and Mewtwo. So other than Mewtwo, it's one of the OU Pokémon; probably Ninetales as the most metagame-defining.
