Based on its stats its either this Breloom:
Breloom
Ability: Technician
EVs: 4 HP / 252 Atk / 188 Spe
Jolly Nature
IVs: 28 Def / 25 SpA / 22 SpD
OR
Breloom
Ability: Technician
EVs: 68 HP / 252 Atk / 188 Spe
Jolly Nature
IVs: 15 HP / 28 Def / 25 SpA / 22 SpD
If its the first one you should be able to have around 64 EVs left over which you can invest in speed.
To know wether it's good in competetive we'd really have to know if it has technician or not, if it does its good. If it has spore then it's definitely viable (As that s the main attraction of Breloom, along with things like STAB technician Mach Punch)
If it has spore, and preferably the first EV spread then I'd go for it, its IVs areb't bad either so yeah, if you wanna use it though, use it.
