In order for Proleiator Invinctus to clean up the Tower before I get Soul Silver, I've created a Speed Team to help me ace the first 49. I've used Pokemon that aren't common on Speed Teams, just to be different.
ScarfLade. Standard as it gets, except that I'm running 236 Speed EV's, simply because it's the minimum ammount he needs to outspeed the highest speed teir he can with Adamant at +1(Scarf).
Porygon-Z. Again, standard. A straight up attacking set is all he can really do. Thanks to AlCario for the changes to Porygon-Z.
And Zapdos to finish. Guards against both Gallade's Flying weakness and PZ's Fighting weakness. Standard LO set.
