Going to be a lot shorter then some of my other peer edits. I used this set to great success when I was taking part of the Uber Metagame.

<p>Darkrai as a lead can simply not be overlooked. With a Choice Scarf, Darkrai will top out his speed at an incredible 493, assuming he is running a Mild nature.This outruns a variety of Uber pokemon such as Timid ScarfKyogre, Timid ScarfPalkia, and even Jolly Rayquaza with one Dragon Dance. Thanks to the Choice Scarf, Darkrai will easily outspeed all of the above pokemon and hopefully cripple them or even kill them. This set functions extremely well as an Uber revenge killer.</p>
<p>The most important attack to this set is Dark Pulse as it gives you not only a STAB attack coming from a base 135 Special Attack, but also can give you that handy flinch which can really save you from defeat. Spacial Rend is a great surprise that also OHKOs Rayquaza and Palkia after you outspeed them. Thunder will decimate Kyogre and Manaphy but beware, Kyogre's Surf will still OHKO Darkrai. Finally, Focus Punch or Focus Blast can be used in the last slot for opposing Darkrai, Tyranitar, Blissey, and Dialga.</p>
<p>IF you plan on using Focus Punch, then using the suggested EV spread will be your best option. However if you do not worry about Blissey and a defensive Tyranitar then use Focus Blast as well as max out Special Attack and Speed.</p>
That should be everything. If it looks a bit messy and worded strangely, I will just reword the article. Thanks.
