Hippodowon is seriously a joke.
Usage: | 39 | Hippowdon | 48756 | 4.88 |
Lead: | 10 | Hippowdon | 22696 | 2.27 |
Ok, lets do some math! 4.8-2.27 = 2.53% to face a healthy Hippowdon, as Leads are most definitely going to be weakened already.
| Hippowdon | Defense EV | High (150-200) | 53.0 |
| Hippowdon | Defense EV | Max | 14.0 |
Something tells me that basically all the Hippodown's used run the standard Smogon sets. Even though running 252 HP / 252 Def is stupid on such a pokemon, I will just assume its sane.
So some more math! 2.53% x 14% [keep in mind they may not be running 252 HP too] = 0.03542% to face a Hippodown running such a set. You can prepare for such a thing if you want.
And I know the Gengar example was silly, but its the principle and it showed what I was trying to demonstrate.
