Nico Nico Nii!~
Except there totally was a Steel-type Eeveelution in EX: Delta Species. Five of them, in fact. See the Jolteon below for an example. Anyway, onto rating the Vaporeon posted.
Artwork: 6/10. Those eyes look a little funky to me.
Playability 5/10. Interesting, but completely outclassed in its time simply because of the existence of Luxray GL and Luxray GL Lv. X.
Collectibility: 4/10. It's a rare, but it's not from a presently sought-after set.
