The ground ghost pokemon could change up the leads we see in OU. It gets No Guard in the dream world.
Klutz can be devastating if it learns trick.
Iron fist means it most likely can learn dynamic punch.
That means that No Guard + Dynamic Punch = great lead. It can attack ghost type switch ins with its STAB. In addition, it is immune to fake out and explosion and even to dynamic punches from machamp. If we can there is a Stealth Rock Tutor or if there is a way to transfer TMs, I'm sure he learns Stealth Rock. with 89/80/80 defenses, it can survive hits from many other leads. It gets 124 Base Attack, which is really high. Its only let down is its base 55 speed, which makes it slow. But based on the other BW pokemon we saw, 55 speed isn't too bad.
