Pluck doesn't steal berries, or atleast not in the sense that your guide wants it to steal berries.
Pluck uses the berries effect right away.
EDIT:
-Ribbons
The Effort Ribbon from R/S/E is the same as the one in D/P.
Also, there's no mention of the "National Ribbon," you get for purifying a shadow Pokemon from Colloseum/XD and transferring over, or the 100 straight wins from Mt. Battle, the, "Earth Ribbon."
-Berries
Berries #61-64 are all listed as, "Transfer via Pal Park," but they're all new berries. Do you get them as a prize for a really high score, or is this just a placeholder?
