I mean Pokemon that can only be caught as a static encounter.
For example, arctibax can only be found and caught in the wild as a static encounter, even though you can obtain it by evolving frigibax.
The only exclusive one I can think of (excluding through breeding) is spiritomb. Gimmighoul is also only available through static encounters but that doesn't count since it can't be hunted in those encounters.
Oh yeah, if a Pokemon is a static encounter in one map but can be encountered in another map (like eelektross), don't include it.
