-You face a high Defense-low Sp.Def Fire Type (Torkoal or Magcargo)
-You face a high Defense-low Sp.Def Pokemon that resists Bug Type Moves in-general (Aggron, Skarmory, Steelix, Golem, Gigalith)
-Cofagrigus enters hoping to screw you out of further Bug-Type Move boosts or Critical Hit blocking
-Counter and Metal Burst users could 1KO you from Megahorn use
-You could miss entirely (Megahorn's accuracy is 85% and you could be further hindered by Muddy Water, Mud Bomb, or a lucky enemy's Acupressure)

Protecting your Attack from hindrance is as important as KOing any Pokemon that can hinder it. Without your key offensive stat, you will have a ton of issues. Rain + HP (Water) is a safety net.

* Doesn't carry Fire Type Moves outside of a random Heat Wave, but it's very unlikely.
Simple math: HP water + rain = 140 base power (assuming perfect IV which would not be the case outside of PO) * 2 = 280 base power against something SE on it coming from a pitiful base 60 special attack and mosly uninverted meaning it will be like 150 special attack at lvl 100...

VS

non effective STAB megahorn (which you can further boost with swords dance) 180/2= 90 base power from 135 base attack stat his attack stat is mostly inverted and have a chance to be boosted to 180 power again
85 accuracy is more than acceptable (8.5/10 chance to hit).

turn 1: you switch in excavalier in choiced latios with draco meteor (or what ever)

turn 2: they switch to volcarona then you swords dance

turn 3: they use quiver dance cause it sounds stupid that you will stay then you KO with megahorn.. (and if there is stealth rock better)

simple
