It only needs 208speed evs to outspeed scarf timid Rotom-W but I don't really think that Deoxys-S needs the extra speed seeing that it doesn't have anything to hit it with and stuff....
Anyways, I think that your team would benefit more if the Scizor WASN'T the swords dancing one but the Choice Banded one which works well with Rotom-W seeing that they get rid of most of each other's counters and U-Turn/Volt-Switch is very helpful on Hyper Offensive teams where you never want to lose momentum. You could also try Lefties Scizor with same moveset as CB and I think that you should have Choice Specs>LO on Rotom-W because of the usefulness of simply crippling walls with a choice item. Also why do you have CHOICE SCARF GENGAR?!? I don't see how it "trolls" Choice'd Terrakion as the only move that will do decent damage on Gengar from Terrakion is Stone Edge which Lucario 4x Resists.... I would have SubDisable or Possibly Painsplit+3 Attacks with like Shadow Ball, Focus Blast, HP ICE or sumin for Gliscors which your team doesn't seem to like at all. Lastly, I would recommend a moveset of Dragon Dance, Dragon Claw/Outrage, WATERFALL, BRICKBREAK. I think this is better because then you can more easily handle Gliscors which may switch into an Outrage and Brickbreak also hits Heatran + Ferrothorn for super effective damage. Doesn't hurt that Waterfall gets boosted in rain and does more damage to all of those steel types other than Ferrothorn :) Other than that, seems like a great team.
