Duskull, the Requiem Pokemon

I thought up this build at work today, and have not yet tested it, however, in theory, it is unstoppable. This must be done in Generation IV. The move set it will have from the egg should be:

Disable
Grudge
Torment
Night Shade

We will rid Night Shade for the move Spite, which it learns from a Move Tutor in Generation IV.

First, the process;

1) Breed a male Bannete that knows Grudge and Torment with a female Duskull.
2) Raise the male offspring a few levels to make it learn Disable.
3) Breed that male Duskull with a female Duskull that knows Disable.
4) The pokemon that hatches should be a Duskull that knows Grudge, Torment, and Disable. Take it to a Move Tutor to teach it Spite in exchange for a few Shards.

I know the first thought on your mind. "This thing cannot deal any damage with these moves! Do we have to hold an intervention for you?"

First of all, yes, because I'm addicted to BEING AWESOME!!! I just can't get enough of it.

And secondly, look at all these moves on a Dusknoir, Duskull's final evolution. Disable will stop the foe from using one of its attacks. Then use Torment, and the enemy will not be able to use the same attack twice in a row. Then continue to use Spite. Spite reduces the PP of the last move the target used by 4. Include the Pressure ability Dusknoir has, and it just cost the enemy 6 PP to use a single attack. That means you can deplete your average attack in 3 turns. And when you are near death, you Grudge, and that will deplete the PP of the move that knocked you out.

Now the theories as to why this will work(I have not yet tested it, will confirm later). Dusknoir has extremely high Defense and Sp. Defense stats, so it can withstand most any attacks. It only has 2 weaknesses, making it even better for Defense. And Struggle, though it can still damage him despite being a Normal-type attack, will still be subject to Torment, so it will only be able to attack every other turn.

So any thoughts or ideas? They are always welcome.

A thanks to Misty for informing me on the rules of Struggle!
