it's kind of lazy to nom the exact same serp set twice so
Tapu Bulu @ Assault Vest
Ability: Grassy Surge
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Horn Leech
- Wood Hammer
- Stone Edge
- Superpower
Tapu Bulu isn't very good, as a general rule it's probably the least neutral tapu for the least neutral terrain, builds with bulu must be made with grassy terrain being up some of the time in mind, so eq use must be limited, so it's not super splashable.
but god damn if even without super effective coverage bulu wins the matchup.
Breloom is forced to get good Bullet Seed rolls multiple times *while predicting the bulu switchin which means it's not sporing* even if it's Adamant.
252+ Atk Technician Breloom Bullet Seed (4 hits) vs. 252 HP / 0 Def Tapu Bulu in Grassy Terrain: 180-216 (52.3 - 62.7%) -- approx. 99.6% chance to 2HKO after Grassy Terrain recovery
If it's Jolly it has to rely on both predicting the bulu switchin, and getting *double 5-hits* or some combination of high rolls with 4-hit followed by a 5-hit. It's incredibly unlikely if you don't know!
252 Atk Technician Breloom Bullet Seed (4 hits) vs. 252 HP / 0 Def Tapu Bulu in Grassy Terrain: 160-192 (46.5 - 55.8%) -- approx. 6.6% chance to 2HKO after Grassy Terrain recovery
Whereas Bulu... gets em with a simple one-two punch horn leech+superpower. dead mushroom.
