I'm not saying it's balanced, because this will probably be the most broken thing to hit OU after Mega Gengar, but it has one switch-in. ONE. Obviously, if rocks are up, even this thing can lose against it LOL. So basically, what I'm saying is you can either run a pokemon with Ice Shard or run Mega Slowbro with a specific spread to not auto-lose against this.
252 SpA Salamence Fire Blast vs. 252 HP / 240 SpD Aggron: 124-147 (36 - 42.7%) -- guaranteed 3HKO
0 Atk Aggron Ice Punch vs. 0 HP / 0 Def Salamence: 188-224 (56.7 - 67.6%) -- guaranteed 2HKO
+2 252+ Atk Aerilate Salamence Return vs. 252 HP / 16+ Def Aggron: 69-81 (20 - 23.5%) -- guaranteed 5HKO
Aggron vs mence.
ANY options u choose make Mence vulnerable to another set of counters.
double + claw + dance + hypervoice/meteor/fireblast
152+ Atk Aerilate Salamence Double-Edge vs. 252 HP / 252+ Def Audino: 174-205 (42.4 - 50%) -- 0.4% chance to 2HKO
+1 152+ Atk Aerilate Salamence Double-Edge vs. 252 HP / 252+ Def Audino: 261-307 (63.6 - 74.8%) -- guaranteed 2HKO
+2 152+ Atk Aerilate Salamence Double-Edge vs. 252 HP / 252+ Def Audino: 348-409 (84.8 - 99.7%) -- guaranteed 2HKO
152+ Atk Aerilate Salamence Return vs. 252 HP / 252+ Def Audino: 148-175 (36 - 42.6%) -- guaranteed 3HKO
252 SpA Salamence Fire Blast vs. 252 HP / 0 SpD Audino: 93-110 (22.6 - 26.8%) -- 33.6% chance to 4HKO
0 SpA Audino Ice Beam vs. 0 HP / 0 SpD Salamence: 236-280 (71.2 - 84.5%) -- guaranteed 2HKO
so either u die from 2 ice beams and deal some damage with return or double edges and dies from collateral damage + ice beam (not considering SR)
Ddance in front of audino is not a safe option too cause he has Encore/toxic/protect Wich mence is extremely fragile. MAudino can safely switch in in many situations and is immune to one of Mence stabs.
Audino Vs mence
252 Atk Lopunny Fake Out vs. 0 HP / 0 Def Salamence: 55-66 (16.6 - 19.9%) -- possible 6HKO
252 Atk Lopunny Ice Punch vs. 0 HP / 0 Def Salamence: 272-320 (82.1 - 96.6%) -- guaranteed 2HKO
Mlopunny vs mence
The problem is (and i've repeated myself many times) is that people are comparing Mmence the same way they tested Mmawile/Mlucario and this cannot be applied, any set (as i said) can only cover/recover/mix/bulk 1 at a time, not all of them.
Mences that survives Mslowbro can be easily countered by Cofagrigus/Ferrothorn/Wow walls
Mences that survives Maudino can be easily revenged by ice shard/fake out/outspeed ice damage
Mences don't surivve swift swin kingdra ice beam in any situation/ Mswampert ice punch(in some situatons)
u cannot easily switch in and out cause the MMence typing don't help u with that (Sr weakness, toxic, Wow, TW weakness, Ddance dependance).
So no, Salamance
DONT have only one check and can be dealt with no specific counter (revenge kills/toxic/stalls/hazards)
IMO declaring Salamence broken before testing is a little too rush.
