Rillaboom @ Life Orb
Ability: Grassy Surge
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Grassy Glide
- Superpower
- Knock Off

Overwhelming amounts of power. Swords Dance to double attack. Grassy Glide for STAB Grassy Terrain boosted priority move. Superpower for steel coverage (like Ferrothorn), and Knock Off to remove items. Life Orb gives even more power, and most of the damage from Life Orb will be recovered by Grassy Terrain.

Dang, you're on a roll with these movesets (lol)!  Nice job!
thanks!
personally, i'd recommend high horsepower. Still a fun set though.
True, that makes sense.
SpillThePolteageist, I'm confused as to why you would run high horsepower over earthquake when it learns both moves. High Horsepower gives no secondary effect, and only has 95 base power instead of earthquake's 100. Maybe in doubles with a grounded ally, High Horsepower would do more since moves that hit everything do less when hitting multiple targets, but outside of that I see no reason to run it over earthquake.
earthquake is weakened in grassy terrain

This is a cool set.
Thanks!
I personally think that this is a good set, however sub swords dance for drum beating, as it gets STAB and lowers opponent's speed.
Glide is also stab, and you lose coverage with sub. Sub is basically never used on rillaboom

Rillaboom @ Darkinium Z
Ability: Grassy Surge
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Swords Dance
- Grassy Glide
- Darkest Lariat
- High Horsepower

Swords Dance boosts your attack. Grassy Glide is STAB that has priority in Grassy Terrain. Darkest Lariat is for coverage. High Horsepower deals with steel and fire types. The Darkinium Z is so that Rillaboom can OHKO Zapdos with a +2 Black Hole Eclispe.

choice band growth/sunny day?
Solar blade over drum beating or wood hammar?
Don't do Solar Blade. 125 base power is great, but it needs to charge up for one turn, which basically lowers it to 62.5, which is bad.
Solar Blade is basically effected by sunlight which if you use will make it stronger
Grassy surge is on the game

Rillaboom @ Leftovers
Ability: Grassy Surge
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Wood Hammer/ Grassy Glide
- Drain Punch/ Knock Off
- Protect
- Leech Seed
Explanation: This set is for Gen 8 OU on Showdown. Wood Hammer is STAB and the power is boosted in Grassy Terrain. Drain Punch is to recover HP, and can heal off the Wood Hammer recoil. Leech Seed is to lower the opponent's HP and steal the grounded opponent's Grassy Terrain's 6% HP restore. Protect is to avoid taking damage and get HP recovery from Leech Seed, Grassy Terrain, and Leftovers.
Move Alternatives: Grassy Glide: if you want +1 priority during Grassy Terrain
Knock Off: useful on Pokemon such as Tangrowth that can wall Rillaboom.

Rillaboom @ chesto berry
Nature: Adamant/Jolly (preference for attack or speed up, both lower special attack)
Ability: Overgrow (look into Grassy Surge once the DLC comes out)
EV's: 252 Attack/252 Speed/4 HP

This set is for those who want to try something out of the ordinary to throw the opponent off their game.

1: Knock Off- good, decent power moved that negates opponents item
2: Drum Beating- rillaboom's special move that increases its speed.
3: Rest- heal up and use the chesto berry.
4: Snore- decent power move to use when you use rest to heal a second time. may cause flinching so you can frustrate your opponent more.

All comments greatly appreciated. I don't play the game on a competitive level that most of you do. But I do enjoy tinkering with Pokemon to see what I can make.

snore with a -sp.atk nature?
Snore in general?
Why Snore? Go for Earthquake.

-Drum Beating/Wood Hammer (leaning towards more wood hammer because of healing)
-Knock Off
-Fake Out/Protect
-Drain Punch

In almost every situation, it's better to max HP than to choose 1 defensive stat. 252 HP EVs are indeed slightly less effective than 252 Def EVs at blocking physical attacks (or 252 SpD EVs for special attacks), but HP EVs affect *both* stats, which makes them almost universal on defensive Pokemon.
Theres actually grassy surge on it now that its released
252 on defense is better because Rillaboom is a physically defensive sweeper, I would put 252 in hp if this was a Dynamax/gigantamax build
hp is better, because it boosts both defenses. do not run max defense

Rillaboom @ Choice Band
Ability: Grassy Surge
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Grassy Glide (70 Base Power Grass Type Move)
- Superpower
- U-turn
- Knock Off

Grassy Glide is basically the strongest priority move in the game paired with STAB + Grassy Terrain. Superpower nails Ferrothorn. U-turn is for momentum. Knock Off can remove items from Pokemon that would basically wall Rillaboom, like Corviknight, Tangrowth (?), etc.

Trait: Grassy Surge
Nature: Adamant (+Attack, -Sp. Attack)
EVs: 252 Attack, 252 HP, 4 Sp. Defense
Role: Physical Tank

Moves:

  • Grassy Glide
  • Knock Off
  • U-Turn
  • Drain Punch

Grassy Glide For STAB, that gets Priority in Grassy Terrain, which is placed when Rillaboom Comes out. Knock Off gets rid of the opponents item which could be really helpful. U-Turn is for switching out. Drain Punch is to gain lost HP

If it's a physical tank, why adamant?

Rillaboom @ Choice Band/Life Orb/Grassy Seed
Ability: Grassy Surge
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Grassy Glide/Drum Beating
- U-turn
- Drain Punch
- Knock Off/High Horsepower
Grassy Glide has priority and deals slightly more damage in terrain. Drum Beating helps Rillabooom's Speed even better, U-Turn switches out Rillaboom when in a bad matchup. Drain Punch heals up Rillaboom while countering it's Ice type weakness. High Horsepower covers Fire and Poison types while not being affected by Grassy Terrain unlike Earthquake. Knock Off knocks off the oppoment's item, which can help a lot, also deals double the damage when Knocking Off an item.
I've hoped I've helped!

Drum Beating should used only for stall sets. Grassy Glide is better.

Why Sunny Day? You can use a auto sun setter. Why Solar Blade? Why Endeavor? Why Bold nature? Bold nature doesn't help since it raises defense but lowers attack. Why do you have special attack EVs when you don't have a special move? Why Focus Band?
I can see what they are doin, but it is a gimmick that relys on rng. Focus band needs ro activate on sunny day, than you can endeavor at one hp or use an overgrowth boosted solar blade. It just fails if they are faster tho, and its a small chance to survive.

Grassy glide stab along with priority when paired with grassy surge ability. Darkest lariat also stab but negates opponent stat boosts ( Defense and evasion ). Swords dance is for powering up when needed. Drain punch is coverage and also recovery. Second moveset btw.
