The Three-Day Eeveelution Extravaganza!

Registration for the Eevee Friendly starts in two days, and I figured that, with an Eeveelution-centric tournament just around the corner, I might as well finally make my post about competitively using the evolutions of Eevee. ("Eevee" + "evolution" = "Eeveelution.") Then, it hit me: there are nine ways that Eevee can evolve, including not evolving at all. So, I'll be spreading this out over today, tomorrow, and the 3rd: the start of registration day. I'd also like to say that the Eevee Friendly tournament puts your Eeveelutions' levels at 30 rather than 50, making it much more manageable if you have to catch more than 2 Eevee to raise into your desired form. (Eevee can be found in the wild in X & Y outside of Geosenge Town, on Route 10, at level 20-22ish.) So, let's get started!

Let's start off by peering at Eevee and its forms. For the sake of simplicity, I'll be referring to Eevee/its evolutions as "he." While I'm not discrediting all of the female Eevee out there-- far from it-- males are statistically more common and it bothers me to use "it." As of Generation 6, these are the existing Eeveelutions:

As you can tell, there's a lot of diversity between Eevee's forms. Today, we'll be talking about Eevee himself, along with Glaceon and Leafeon. (While it might make more sense to do Eevee and two of the original Eeveelutions, I'd rather that they all be on one day.)

Eevee
There's a lot of potential for Eevee, with all of his forms. However, because of Eevee's undetermined future, he can't really specialize in anything. Eevee's stats are generally very similar, though they aren't particularly great in terms of base value; his Special Defense is his best stat, at 65. He's very cute, though.

Leafeon
Leafeon and Glaceon, like Umbreon and Espeon, are siblings in terms of how they evolve. To become a Leafeon, an Eevee must level up when near a mossy rock. In terms of stats, Leafeon is an improvement in base stat value from his previous form, with his best base stat (Defense) at 130. Leafeon also has access to Leaf Blade, which is gets STAB from. If a Leafeon has Chlorophyll and is teamed up with a Flareon that has Sunny Day, he can benefit with the healing...though he's more vulnerable to Fire-types as a result. Leafeon is thought to be outdone by many Pokémon...but I still have one on my Eevee team!

Glaceon
Glaceon, like Leafeon, evolves from Eevee when in a certain area; in this case, near an icy rock. While Glaceon may, in some ways, be outdone by Vaporeon (which has access to Ice Beam), Glaceon does learn Mirror Coat, and can heal during hail-storms with Ice Body (his Hidden Ability). In terms of stats, Glaceon's best stat is his special attack, which sits at 130, as is the case with all Eeveelutions and their best base stat. Glaceon does suffer a shallow move-pool issue like Flareon, though his issues arise in the case of special moves.
