How does Vaporeon benefit from the sun? All it gets is less accurate Thunder at the cost of 1-turn Solarbeam and weakened Hydro Pump. Jolteon gets nothing but positives except for bad Thunder accuracy. If I were you, I'd put some sun-team based Fire-type. If you had a Rapid Spinner, you could try to use Charizard, but none of the Eeveelutions learn Rapid Spin. I guess I'd go for Heatran, Infernape, or Venusaur as another Chlorophyll user. I left out Volcarona because you hate using it, but you can use that too. (Ninetales makes it OU, so I focused on those).
