Life Orb Adamant Techniloom is what I use and it's the best Breloom set imo.The sheer power and offensive presence of this set very standard set makes it such a threat imo.Toxic Orb sets are really good too,But techniloom is really the selling point.If you compare the usage stats of pre techniloom time you'll see what I mean.
There is one set I battled against and it really took me by surprise.Then I used it a bit.
Breloom (M) @ Choice Scarf

Scarf Loom!Breloom at first glance is not a very good scarfer.But what makes this set to be effective is surprise factor.Imagine you're about to KO Breloom with your Torn-T and suddenly the mushroom outspeeds and spores you.If you don't have something for back up,this could mean disaster.The ScarfLoom I faced Spored my DDMence and went to town against my Terrakion,Keldeo and Landorus with Bullet Seed.Really when you are able to surprise spore their Breloom check/counter Breloom becomes extremely threatning.
These set also outspeeds Adamant Dnite and Gyarados at +1 so fuck yeah.Bullet Seed and Low sweep is the obvious powerful STABs while Stone Edge provides useful coverage.You will be astonished by how many surprise kills this boy can get.But when you spored something and blown your cover,with Sleep clasue ScarfLoom becomes slightly medicore.
