Comments

So you did took part of my advice speed freak dident you ?

Answer 1

Baton pass would be good for leafeon so when it gets low, instead of healing you could switch out, if you used swords dance, and give that stat raise to umbreon or something. And I would go with vaporeon first and raise defense, then baton pass it to leafeon, then baton pass it to umbreon, after that play out the battle and if he goes down go with whoever you need to next.

Answer 2

Seems Good. I'd Actually Go Grass Knot Over Signal Beam on Espeon though.
Lead With Leafeon, and go with baton pass over Synthesis.

Answer 3

Seeing that your Leafeon has Swords Dance, there is no need for Baton pass because all the others have special attacks!
