GamePress's fast move page has an entry for Smack Down. But it appears to be an exact copy of Rock Throw - all the specs are the same. Is that just a placeholder, or has someone datamined the code and found the exact values?
Just caught a level 32 763cp with 10a/14d/14s...so that is one good enough for me to quickly evolve on Community day (have 135 candies). I went into charmander day with no decent candidates and never found a high level nor great one either.
