This is by far my favourite Breloom set in this metagame. It requires prediction to bring in safely, but once it's in it can create enormous offensive pressure on the opponent. Although it lacks the raw power of the SD set, what it does offer is the ability to gain momentum. Many of Breloom's usual switch-ins, such as Tornadus-T and Lati@s, cannot deal with the speed drop from Low Sweep. With Jolly nature, you essentially have 393 speed after hitting something with Low Sweep. Bullet Seed will hit even resists hard if it hits 4/5 times.
I'm not sold on the choice sets to be honest, as Breloom is mostly outclassed when it comes to pure attacking power by Terrakion. Spore should be mandatory on all Breloom sets imo; without it, you're missing out on one of its biggest niches.
