Are there any Pokemon with solid base stats but outclassed into oblivion?
I guess Arcanine.
Are there any others?

But then poison would have only one weakness, to ground. That's why the new types added were a necessity, for balance. If they had only switched things around, it wouldn't be balanced. Psychic's OP factor was mitigated by the introduction of dark, and dragon's OP factor was mitigated by fairy. Steel affected both, being resistant to those types (and also dark), and immune to poison, while not super effective against them (but it and poison are effective against fairy, keeping any one type from being too OP).
And really it was less that psychic type itself was overpowered, and more that Special Attack and Special Defense didn't exist and were both calculated from the singular Special stat, making mons like Alakazam (with its also very high speed) ridiculously OP.
