Rayquaza is notoriously difficult to handle. This set truly exemplifies that fact, the only reliable switch in into this is defensive Heatran, but using that on a sand team against what is probably going to be rain is suicidal. Steel Arceus is probably your next best switch in, but takes a toasty offering from Fire Blast and restricts Arceus typing. Not to mention Kyogre beats Steel Arceus on most occasions.
Draco Meteor OHKOs Hippowdon, 2HKOs courageous Gastrodon, and pretty much slices a rather large chunk out of most Pokemon. Fire Blast actually packs a surprising amount of power, still OHKOing Specially Defensive Skarmory at -2. Outrage prevents Blissey and Chansey from walling this set and in conjunction with Dragon Dance can threaten a sweep if such an opportune moment presents itself.
This also forces a Choice Scarf user upon team 2, because Excadrill cannot revenge kill Rayquaza.
