1's Reason: Because it's fast and powerful. Also good for me because I like Psychic types.
2's Reason:Because It has a lot of Defense, and that's what I need in every battle in order to Survive. Seconded because has weak power and Strong defense, and is one of my second favorite types, Dark.
3's Reason:Fast, Pin missile is part of its attacks, and I like it. Good at speed and attack, and is Electric, which that means that Electric is top for me because it has only one weakness; Ground.
I actually like all of the Eeveelutions, Generally, Eevee, because the poor thing gets trashed down by the others. It's only quite cute and lovely, but not good for battles. In fact, an Eeveelution CAN defeat this thing easily. :(
