I'll probably be unable to test this set, so if others want to then by all means go for it. It's a variation of one of the sets in this Pokemon's analysis, and I based it around SubPetaya Empoleon.
Beedrill @Liechi Berry
Swarm | Adamant | 4 HP/252 Atk/252 Spd
~ Substitute
~ Agility
~ X-Scissor
~ Brick Break/Pursuit
If you know how SubPetaya Empoleon works, you know how this works. Luckily, 4 HP EVs is all it takes for Beedrill to get HP divisible by 4, which is convenient. Anyone know if this would be good from a theorymon point of view? Or would it be outclassed by something else?
