I think it's interesting to note that at +4, Hydreigon has a chance to OHKO common Heatran spreads with Draco Meteor after slight chip. Many of the spreads I've seen running around in RMTs these days are 252 Hp 128 SpDef Calm. Heatran can do very little back to Hydreigon, as we've seen in the spdef sets, so getting that second Nasty Plot boost isn't as hard as it would be for another sweeper such as Pheromosa or Kartana.Hey guys so I was looking trough Hydreigon's movepool and found out it gets Shock Wave. Forget Hyper Beam. Shock Wave is the best move to hit Tapu Fini. 60 BP may seem bad at first but when it's boosted by Life Orb and coming off Hydreigon's good Special Attack and when it hits for super effective damage it almost knocks out 252 HP Fini in one hit at +2. It may kind of suck that you're running a move for just one Pokemon but Tapu Fini is a very common presence in the tier almost in the top 10 most used Pokemon so I think it's a move worth running on offensive Hydreigon sets. Shock Wave is also good for Pelipper, Slowbro, Togekiss, chipped Toxapex and chipped Mandibuzz because you don't have to waste a Draco Meteor and be forced out after. Clefable and Magearna do not like switching into Fire Blast at all. If you're feeling up to it you can run Modest Hydreigon to squeeze a little more juice from Shock Wave and you actually have a chance to OHKO Phys Def Clefable at +2 with a Fire Blast.

This leaves you sort of walled by Heatran and Tyranitar and Blissey are annoying but Hydreigon can only cover so much at once. But the first 2 lack recovery and hate taking boosted Draco Meteors anyway.
