oh smogon, why can't you understand a good set when it's right in front of your face...
Breloom (M) @ Fighting Gem
EVs: 68 HP / 224 Atk / 212 SDef / 4 Spd
- Swords Dance
- Bullet Seed
- Mach Punch
ok hello, this right here is the best breloom set, fight gem is far superior to mach punch for so many reasons, most notably of which is the massive damage it does to stuff that likes to switch into it. for example,
224 +2 Atk Fighting Gem Technician Breloom (+Atk) Mach Punch vs 0 HP/0 Def Latios: 63.46% - 74.75%
latios being the favored switch-in to breloom after it spores something, assuming it goes for the SD on the switch, meaning all you really have to do is make latios take a couple layers of rocks, after that it's gg assuming your opponent doesn't have a secondary breloom check, and even if he does you've still done some serious work to his team. 1 pokemon asleep, another one dead, a third probably taking some mach punch damage. evs let loom live a life orb icy wind from keldeo, as well as jolly terrakion's close combat. kickass spread if i do say so myself, thanks to princess bri for it.
give fighting gem a shot, it's better than life orb because it nets that one kill that's always inhibiting breloom from sweeping.
