I've been having quite a bit of fun with this set
Breloom (M) @ Life Orb / Fist Plate
Trait: Technician
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature
- Mach Punch
- Focus Punch
- Bullet Seed
- Spore
You know what's really funny? Sporing something, having the opponent switch in their Lati@s to take the Mach Punch/Bullet Seed/scare it away after it sets up Swords Dance, and finally watching them cry when they get raped by the 150 base power STAB Focus Punch coming off of 394 Attack. Focus Punch does 252+ Atk Life Orb Breloom Focus Punch vs. 4 HP / 0 Def Latios: 211-248 (69.86 - 82.11%) -- guaranteed 2HKO, which, when followed by a Mach Punch after Stealth Rock, is essentially a OHKO, and even without Stealth Rock, at worst, Latios is looking to be at 4%. LO Latias takes (63.24 - 74.5%) from Focus Punch, and (25.49 - 29.8%) from Mach Punch, which is also a guaranteed KO after Stealth Rock, and without Stealth Rock, leaves her at about 11%. Even Specially Defensive Celebi (considered one of the best counters to Breloom) takes (43.31 - 51.23%) from Focus Punch, which is nothing to scoff at. You lose the ability to set up and sweep teams, but you absolutely destroy walls, and can still clean up late-game with Mach Punch. But with Spore and the presumed switch in on Focus Punch, you're looking at two Pokémon eliminated by Breloom
at least. I've been having a ton of fun with this set, and I highly recommend it.
