Cobalion's Base 108 Speed lets it outspeed every relevant scarfer in UU, making it scary to deal with at +1. Rock Polish is on the standard set, and that can be better in some situations because it lets you set up double dances more easily while also giving you the option to run a resist berry or Lum Berry to make it easier to setup. However, Cobalion's speed means you really only need +1. Salac Berry thus does not cost you much in terms of speed, and it is much easier than Rock Polish to activate because it does not require an extra turn of setup. Cobalion's bulk and typing also mean that it is bulky enough to survive many super effective attacks and activate Salac Berry. If Cobalion has taken about 10-20% chip [which it often does] and is in versus a Noivern, for example, Cobalion can SD as Noivern attacks, live its attack (hurricane does 60-70, flamethower does 66-77), activate Salac Berry, OHKO it, and then sweep thru offensive teams.
As an added bonus, it quad resists First Impression, making it an especially threatening Speed-boosted sweeper. Look at this absolutely comical calc of a hypothetical attempt to revenge it:
252 Atk Choice Band Mold Breaker Haxorus First Impression vs. 0 HP / 4 Def Cobalion: 32-38 (9.9 - 11.7%) -- possible 9HKO
A 12% Cobalion is still too healthy for Haxorus to revenge, which is hilarious.
You still get walled by Cobalion's usual counters, most notably Doublade and Golisopod. However, Substitute allows you to get up more SDs versus some defensive checks, like Rotom-Wash, that stop Cobalion by switching in, living an attack, and burning it.
I honestly didn't expect this set to be so good versus offense, but if it doesn't get matched up versus Doublade it can put in a crazy amount of work. Thought this would just be fun but will seriously consider using this on real teams!!
