In this fast meta after putting a poke to sleep, Stun Spore can cripple the incoming swich-in, like the genies, Genesect or whatever

Trait: Technician
EVs: 232 HP / 252 Atk / 24 Spd
Adamant Nature (+Atk, -SAtk)
- Spore
- Stun Spore
- Mach Punch
- Bullet Seed
Evs are pretty standard, 24 in speed to outspeed defensive Politoed, Atk is maxed out and the remaining Evs are putted in Hp for a little bulkyness.
Fight Gem is here for a well timed Mach Punch having the strenght of the Cbander
Life Orb can be used to improve Bullet Seed also.
