Keen Eye usage and stats in Smogon XY Doubles OU

This Pokémon cannot have its accuracy lowered.

This ability does not prevent any accuracy losses other than stat modifiers, such as the accuracy cut from fog; nor does it prevent other Pokémon's evasion from making this Pokémon's moves less accurate. This Pokémon can still be passed negative accuracy modifiers through Heart Swap.

Overworld: If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.
