Not all spreads made it past the slate. I decided not to choose yours because I thought it was a bit too similar to some of the other ones. Please keep submitting stuff in the future though! You'll make it to slate sometime; I'm sure of it =)
With 31 Speed IVs and no EVs, it'll have a Speed of 15. With 228 Speed EVs, a Speed boosting nature, and 31 IVs, it'll have a Speed of 19. This makes sense because Misdreavus (who has a base Speed of 85), will do the same, just with 236 EVs.
