Munna, the Dream Eater Pokemon

Isn't it cute? So full of flowers and other happy things. It's so peaceful. In fact, this one doesn't even attack.

Calm Mind
Double Team
Baton Pass
Yawn

EVs: 252 Defense, 200 Sp. Defense, 58 HP

Nothing ingenious here, it's just a Baton Passer. Yawn to put the enemy to sleep, Calm Mind to up your Sp. Attack and Sp. Defense, Double Team to up your Evasion, then Baton Pass to switch it all to another Pokemon that could use it more. Musharna has impressive Wall stats and can get away with doing this sort of thing.

How to get it? Well...

(1) Raise a male Watchog to lv 39 to teach it Baton Pass. Teach it Double Team via its respective TM.
(2) Breed it with a female Musharna to get a Munna egg with those 2 moves. Aim for a Nature that lowers either Attack, Sp. Attack, or Speed(you won't be using any of these stats), preferably one that raises Defense or Sp. Defense as well.
(3) Teach the baby Munna Calm Mind via its respective TM.
(4) Raise the Munna to lv 7 to teach it Yawn. Then you can use the Moon Stone to evolve it whenever.

That's it really. You should probably have it hold the Leftovers item so it can recover from whatever damage it takes while the enemy is not Asleep. When battling, start using Double Team before Calm Mind, so that your enemy will have a hard time hitting you once they wake up, so Leftovers can do its work. This build would do wonders to Baton Pass to the Whimsicott that was posted a while ago. All the stats that this Musharna raises are good for compensating for weaknesses in the Whimsicott.

Comments/questions are always welcome. I know I am abandoning Musharna's solid Sp. Attack stat in this build, but I think it is worth it in this case. It can provide a solid stat boost to any Pokemon.

Brock out.
