Cottonee, the Cotton Puff Pokemon

I recently bred Cottonees because of an ability that only they and the Cloud Legendaries have; Prankster.

Prankster is an ability that allows you to attack first as long as it is a Status Attack, that is, an attack that does not directly do damage to the reciever, such as Leech Seed, Double Team, or Confuse Ray.

The Cottonees come out of the egg with the following moveset;

Giga Drain
Grasswhistle
Cotton Guard
Dream Eater

And now the Process to get these beauties on YOUR game!

1) Breed a female Cottonee with a male Sunkern that knows the move "Grasswhistle". Breed for a male Cottonee.
2) Raise that male Cottonee to lv 37, so that it learns Giga Drain and Cotton Guard, and teach it Dream Eater through the TM. This Cottonee should now have the required moveset, however, it has missed out on the superior stat increases a Whimsicott would have.
3) You'll need to repeat step 2 with a female Cottonee, unless the female Cottonee you previously used already has Giga Drain and Cotton Guard. If that is the case, let's move on.
4) Breed the male Cottonee(whose moves should be Grasswhistle, Giga Drain, Cotton Guard, and Dream Eater) with the female Cottonee(whose moves should include Giga Drain and Cotton Guard).
5) Continue breeding until you get a male Cottonee with the Prankster ability and a Nature you perfer, something that lowers your Attack stat is perfect, since it will not be used.
6) Evolve by using a Sun Stone to get a lv 1 Whimsicott that will be able to grow to its full potential.

Why should a Cottonee have this moveset? Because it makes for an excellent Defense pokemon. Allow me to explain.

Because of Prankster, you can put the enemy to sleep with Grasswhistle before he can hit you, which is very important because Grass pokemon are overall the worst type due to their weaknesses. Sleeping pokemon cannot atack you. After the enemy is asleep, use Cotton Guard twice, your Defense stat will then be maxed out, at 400%. Dream Eater is a powerful attack that can be used to drain HP from your enemy, however, it can only be used while the enemy is asleep. Giga Drain is just like Dream Eater, except the enemy does not need to be asleep. "Why should I have both Giga Drain an Dream Eater if they do the same thing?" you ask? In Generation V, an ability was introduced, called Sap Sipper, and  it prevents damage by Grass-type attacks. Dark-type pokemon are fully immune to Psychic-type attacks. There is no Dark-type Pokemon with the Sap Sipper ability, so you will always be able to damage your opponent.

So this is my build for a Cottonee. Grass-type pokemon are scarcely good because of their weaknesses and low move-type variety, but this is one that can last in battle. I am open to your thoughts on Cottonee breeding of course.

Brock out.
