>>13222784Leafeon should be out, since unlike Leafeon, Flareon has usable Special Attack. Grass is only good against Water/Ground pokemon and it's not such a big deal if there's one type combination you can't handle. Just kill those with Espeon's strong stab for example.
But I think Glaceon should be out, because Vaporeon can learn ice beam anyways and Umbreon is a better special tank than Glaceon.
