Everyone wants Ditto and Eevee Friend Safari I understand why people want Ditto (because of the IVs) but I don't get what's so special about Eevee's in Friend Safaris
All of the eeveeulutions HAs are useful some way or another. However there is one particular Eeveeulution which is very commonly used in WiFi battles : ![enter image description here][1]
Sylveon :D
Sylveon's Hidden Ability is Pixilate.
Pixilate causes all Normal-type attacking moves used by the ability-bearer to become Fairy-type. Fairy-type Pokémon also gain STAB from those moves
It also happens Eevee gets access to Hyper Voice. Hyper Voice has a BP of 90 and 100% Accuracy. It also hit all the Pokemon on the opponents team and this is incredibly useful in Double Battles. This makes Sylveon are Pokemon that many people are fond of and need the HA Eevee to breed and then evolve into a Sylveon.
This is just my guess on why they'd be popular xD [1]: https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTe9p01_0SCBuZwbDPv5ynB0OYuXb7FaBOOiKsqDckqQSG4_cyKmg
Who said eevee in friend safari was special? The eevee in a friend safari is a wild Pokemon just like on route 10.
I'm guessing people think it is special because in past games eevee usually required you to complete the game or finish your pokedex and then you only got one of them. So in the past eevee has been relatively rare. It would be like having starter Pokemon in your friend safari.
XY is only the second game to give you eevee as just another wild Pokemon (The first being a hidden park in Black/White 2). So I think people just get excited about it because eevee was rare in the past and they forget it's not nearly so difficult to obtain in Gen 6.
