Rayquaza-Mega @ Sky Plate
Ability: Delta Stream
EVs: 252 Atk / 4 SpA / 252 Spe
Naive Nature
- Dragon Ascent
- V-create
- Draco Meteor
- Toxic
Basically mixed ray but with sky plate and toxic, sky plate allows you to bluff scarf and lure in steels and fat dragons like celesteela, dusk mane, steelceus, zyg and gira. toxic allows it to beat lugia 1v1, which is usually the main ray switch-in on lugia stall, and allowing it to easily break holes in those kind of teams. it also helps ensure rolls vs max def supportceus, and also helps bluff scarf.
As much as I like the set, bluffing scarf with sky plate doesn't work in practise if the opponent knows how to use a pokemon calculator. For example, looking at this calc 252+ Atk Sky Plate Rayquaza-Mega Dragon Ascent vs. 252 HP / 204+ Def Ho-Oh: 267-315 (64.1 - 75.7%) -- guaranteed 2HKO after Leftovers recovery and this calc 252+ Atk Rayquaza-Mega Dragon Ascent vs. 252 HP / 204+ Def Ho-Oh: 222-262 (53.3 - 62.9%) -- guaranteed 2HKO after Leftovers recovery, the min roll of sky plate is still higher than the max roll of scarf. I don't mean to critique the set or say it's bad I just think the idea of bluffing scarf in general with sky plate is misleading and doesn't work.

Adamant Nature
- Swords Dance
- Dragon Dance
- Dragon Ascent
- Earthquake
This is a variation of ice's dd draco set. The advantage of using this set over DD Draco is that you're able to nuke Celesteela much easier due to access to Swords Dance. DD Earthquake is not really capable of breaking Celesteela but SD certainly is, if you SD on the switch and then SD again the roll is in your favour to OHKO (calcs below). By using SD you still retain the ability to OHKO Zygarde and Giratina, and while it's not quite so good against Tar if you can predict correctly EQ is a 2HKO. Another nice thing about this set is you don't have to run a spdef nature so it means you can set up slightly easier on support arc forms such as Ground and Dark. Finally, the main advantage of this set is that you're able to nuke max defence arc forms after an SD, which would ruin your sweep otherwise. This set is great as SD and DD can be used against different teams to great effect, SD against more bulkier balances/semi stalls and DD for more BO type builds. It just gives you more flexibility and you're almost guaranteed to deal damage with this set against almost any team.
