In Pokemon X and Y, if you use Sweet Scent or Honey, you have 100% chance to encounter a Horde. A Horde is a group of 5 Pokémon at a level around one half of the Pokémon you can encounter at the same location in regular one-on-one encounters. Method is not listed as this works in tall grass and caves only. Recommended for fast and easy maxing stats.
Special Attack
Vanillite
Location: Frost Cavern
Encounter Rate: Common
Level: 20
EVs: 1 Special Attack per each
Smoochum horde can be found in Frost Cavern as well. It’s very rare, but the EV yield is the same as Vanillite’s, so you can just use them if you find them.
Speed
Wingull
Location: Route 8
Encounter Rate: Common
Level: 9
EVs: 1 Speed per each
Taillow horde can be found on Route 8 as well. It’s very rare, but the EV yield is the same as Wingull’s, so you can just use them if you find them.
In case it’s raining on Route 8, you can’t use Sweet Scent and Honey to encounter hordes. Alternatively, use:
Zubat
Location: Connecting Cave
Encounter Rate: Common
Level: 8
EVs: 1 Speed per each
Ways to Modify EV Gain:
Pokerus – Doubles EVs gained, can be combined with Macho Brace and Power Items.
Macho Brace – Doubles EVs gained, halves holder’s Speed, can be combined with Pokerus.
Power Items – Gives 4 additional EV's points to a corresponding stat, halves holder’s Speed, can be combined with Pokerus
In Pokemon X and Y, you can find Macho Brace lying on the ground at Route 15, Power Weight (+HP), Power Bracer (+Atk), Power Belt (+Def), Power Lens (+SAtk), Power Band (+SDef) and Power Anklet (+Speed) can be purchased in Battle Maison (Kiloude City) for 16 BP each.
