Luvdisc definitely needs an evolution; its stats suck. There's also Farfetch'd for the same reason. Also, Woobat/Swoobat seem to me to be the Unova equivalent of Zubat/Golbat/Crobat. Therefore, I think Swoobat definitely needs an evo, especially with Swoobat being mainly a Sp. Attacker, but only having a base Sp. Atk. of 77. I think if Swoobat gets an evo in a future generation, it would most likely be with a new evolutionary stone since Woobat evolves via happiness.
