You know what?
Steel and poison type moves are super effective against Fairy type Pokemon.
Remember the other revealed eeveelutions?
Dark with Psychic
Grass with Ice
All had a supereffective counterpart.
Poison does not effect Steel.
If we're lucky, a poison or steel eeveelution will be in 6th generation too.
If we're REALLY lucky, they'll have both types of eeveelutions.
Let's stay tuned and find out!!!
