IDK how this works but i have an idea for an strategy for clefairy, one that im actually using.

[gaboflandre]

My idea is this:
A Bulky Clefairy with EVS in Defence, SP Defense and HP (i dont remember the amount, but it was square) , Equipped with Eviolite, and the moves are:
-Cosmic Power
-Minimize
-Moonlight
-Stored Power.
