With the shift to Sword & Shield Moody was nerfed to no longer be able to boost evasion or accuracy. It will instead boost the other stats a bit more often (1/5 instead of 1/7). Moody was originally banned for being an uncompetitive ability that caused Pokemon to be able to snowball easily through sheer luck with evasion boosts. And I suppose it also borderline broke the evasion clause.
Now that Moody no longer boosts evasion, I question the uncompetitive nature of Moody. Evasion boosts were one of the primary reason you ever had time to amass enough boosts for the Pokemon who gets it to become threatening. With that gone I don't see how any of Glalie, Octillery, Snorunt or Remoraid is going to stay in for enough turns to be a consistent threat.
