Well, after a lot of work, I think I found a counter to Snake's Cyclohm:
Electivire @ Assault Vest
Ability: Motor Drive
EVs: 4 HP / 252 Atk / 80 SpD / 172 Spe
Adamant Nature
- Wild Charge
- Cross Chop
- Earthquake
- Ice Punch
252+ Atk Electivire Earthquake vs. 68 HP / 0 Def Cyclohm: 202-238 (54 - 63.6%) -- guaranteed 2HKO
Okay, now this gets tricky w/ Cyclohm, because it's using Draco Meteor, which gives it -2 SpA each time (obviously).
Electivire has 292 HP.
252 SpA Cyclohm Draco Meteor vs. 4 HP / 80 SpD Assault Vest Electivire: 135-159 (46.2 - 54.4%) -- 53.1% chance to 2HKO - Max roll: 159
-2 252 SpA Cyclohm Draco Meteor vs. 4 HP / 80 SpD Assault Vest Electivire: 67-79 (22.9 - 27%) -- 42.8% chance to 4HKO - Max roll: 79
-4 252 SpA Cyclohm Draco Meteor vs. 4 HP / 80 SpD Assault Vest Electivire: 45-54 (15.4 - 18.4%) -- possible 6HKO - Max roll: 54
The max rolls add up to 292 HP damage, meaning that for Cyclohm to take down Electivire, it has to max roll with Draco Meteor 3 times in a row.
