I have been testing out the Defensive defog set out alongside dugtrio, magnezone, Zard-X, clefable, and toxapex. Defensive defog has been putting in some great work. It takes hits like a champ and can U-turn or shackle back and set the stage for a sweep with clefable or zard. The mon certainly has the 4 move set syndrome where I'd want a grass type attack and defog without losing the other features of the mon, but its still a very viable mon in OU. After Phermosa gets the hammer, this will see plenty of play
