Duosion

When looking at Duosion's stats, its sky-high Special Attack stands out the most. It is one of the best Calm Mind users in the tier, mainly because of its great ability Magic Guard, which makes it immune to entry hazard damage and, more importantly, status, so it is a great win condition for balanced and defensive teams. Its Speed, however, is incredibly low, so it needs Trick Room to outspeed anything. It's also quite frail, so it needs Eviolite to survive any hits. Its typing is also mediocre, with a huge weakness to Knock Off, and it faces some competition from Calm Mind Clefairy, which has similar bulk and access to Thunder Wave, although Duosion is much stronger.
