I've been keeping a new set to myself for about a week prior to Latias being banned in the event that it was. I'd like to share it with you now:
Salamence @ Choice Specs
Naive/Hasty, Intimidate
4 Att / 252 SpA / 252 Spe
Draco Meteor
Hydro Pump
Fire Blast
Outrage
As you can see, this is simply a specsmence with outrage on it. However, where this differs from the prior specsmence is the key to this set. Prior to Latias being legal in OU, Salamence was given Choice Specs as specsmence rather uncommonly, but rather used as mixmence. Prior to that, Salamence was commonly seen with Choice Specs. However, the difference is not the functionality, but rather the differences in metagame. When specsmence was the popular option:
- Blissey was #2 in usage, with Garchomp at #1 in usage. This means that the standard specs set was hard countered by the #2 most used Pokemon in the game, as well as hit super effective and OHKOd by the #1 most used pokemon in the game.
- Because Blissey usage was so high prior to the current metagame, there was a significant chance that any given team had a Blissey on it ready to counter your Specsmence. Now, Blissey is more or less exclusive to stall teams.
- Other pokemon in the given speed range often used higher speed investment than they do now. Generally speaking, the only pokemon that run that speed range now are Salamence and Jirachi. Salamence no longer can get away with 299 or 308 speed, but 328 is necessary. However, other Pokemon that run 306 such as HP Ice Zapdos no longer do for the most part and don't have to be accounted for.
- Since Garchomp was banned, teams no longer commonly carry 3 ice attackers. Without Latias or Garchomp, Salamence only fears dragon type attacks from other Salamences. This effectively means that, for OU, Salamence lost a significant amount of pokemon from it's threat list.
- With Latias and choice Garchomp banned, there is much less incentive to use 3+ steel pokemon per team, making Draco Meteor KOs much more viable in the long run.
-Finally, the specs set was common and thus expected frequently. With the advent of Latias making Specsmence strictly inferior, Specsmence dipped under the radar regardless of Latias's fate from that point on. Specsmence is once again a legitimate surprise.
This Salamence can still break walls to some extent and 2HKOs Blissey with Outrage after SR damage about 75% of the time (130 Def/ 688 HP) so in the event that you get a stall team down to Blissey as its last Pokemon you still have a way to win. Either Hasty or Naive can be used, but I prefer Naive to keep dual Intimidate switches viable when used in tandem with Gyarados. Moreover, it's a tried and proven set in the first place.
