With the nerf to Moody in SS removing its ability to boost evasion, Smogon decided to retest Moody by unbanning it for the new generation, as the historical reasons to ban Moody in Smeargle, evasion, and Baton Pass were all invalidated. However, it has become clear quite quickly that Moody remains uncompetitive in Monotype even if it isn't as broken as it once was. Even though it cannot get free evasion boosts anymore, it now has a 1/5 chance to boost Speed, which is a powerful way to improve consistency with Substitute giving extra turns to boost further. For many teams, stopping Moody users is a matter of getting lucky enough against its Moody boosts before it gets out of control, since Moody is very much a snowbally ability. The more Defense, Special Defense, and Speed boosts a Moody user gets, the more difficult it becomes to stop. When the Moody strategy turns the game into a question of whether the user gets the right boosts at the right times, that is a clear indication that it is uncompetitive. As a result, the council has decided to ban Moody from Monotype once again.
