This is due to the dominance of Zoroark GX (which hits Dawn Wings Necrozma for weakness), the popularity of Garbotoxin Garbodor (which shuts down Psychic Recharge), and the crippling effect of Parallel City taking away Malamars precious bench space, not to mention how the Psychic-weak Buzzwole somehow still manages to beat it half the time
