Strategy
Riolu has access to Roar, Copycat, and the ability Prankster. After I use Roar, I can spam Copycat, which uses the last move used (Roar) and gets +1 priority from Prankster, allowing me to endlessly phaze through opponents who don't have priority and rack up insane hazards damage. This is really gimmicky but can be really effective if pulled off well. I could actually use this strategy in any tier, including LC, but I felt it would do well in NU. This team has been working pretty well for me, but of course it struggles if any of the required portions of set-up are shut down, since I need to dedicate a few spots for support.
Riolu @ Leftovers
Trait: Prankster
EVs: 252 HP / 252 Def / 4 SDef
Impish Nature
- Copycat
- Roar
- Drain Punch
- Crunch
In NU, I don't have to outspeed any other opposing priority users (as far as I'm aware after a little research, could be wrong of course), so I need all investment in bulk in order to survive and get off that first Roar. Max physical defense because opposing priority is what stops Riolu, and all (I've never seen anyone use Vacuum Wave) priority is physical. Drain Punch is actually good against Linoone and just in general to get recovery, and Crunch is kind of there for awkward coverage, although I never really use it. I'm not sure whether Crunch or Substitute is better, or even Bullet Punch (probably not since not STAB and so little Attack). Either way, I never really use that fourth move. I actually think Leftovers is more useful than Eviolite. The most powerful priority, Toxic Boost Zangoose's Quick Attack, does roughly 15% more to Riolu if it isn't holding Eviolite (~30% to ~45%). So, that extra damage can pretty much be healed off with two turns of Leftovers, and I have a lot of time to get tons of Leftovers recovery.
Gardevoir @ Light Clay
Trait: Trace
EVs: 252 Spd / 252 HP / 4 SDef
IVs: 0 Atk
Timid Nature
- Memento
- Reflect
- Light Screen
- Taunt
This is how I help ensure my Riolu survives to get off a Roar. After screens and Memento, the opponent is essentially at 25% power and pretty much unable to take out Riolu. A fast Taunt ensures that I don't get Taunted myself or the opponent doesn't pull off anything sneaky in general. I have used this Gardevoir set to great success on other teams and I love it.
Garbodor @ Rocky Helmet
Trait: Aftermath
EVs: 248 HP / 252 Def / 8 SDef
Impish Nature
- Spikes
- Toxic Spikes
- Pain Split
- Rock Blast
Riolu absolutely requires entry hazards, and I also needed a way to get rid of Toxic Spikes which shut down Riolu. Garbodor's bulk allows it to set up multiple layers often, plus it absorbs Toxic Spikes when switching in. In addition to those two things, there is a ridiculous amount of passive damage that Garbodor can inflict.
Golurk @ Leftovers
Trait: No Guard
EVs: 176 HP / 168 Atk / 164 Spd
Adamant Nature
- DynamicPunch
- Stealth Rock
- Shadow Punch
- Earthquake
Just Spikes isn't good enough because Levitators and Flying-types will never take damage, so Stealth Rock is a must. I also need a spinblocker, because of course, if the hazards are spun away, this team falls. DynamicPunch is chosen because confusion helps my other utility Pokes do their jobs more easily. Iron Fist and Ice Punch may be better for me though. I probably need opinions and further testing on that one.
Primeape @ Choice Scarf
Trait: Vital Spirit
EVs: 252 Spd / 252 Atk / 4 Def
Jolly Nature
- Close Combat
- U-turn
- Stone Edge
- Punishment
Once Riolu has done its job, the opponents will likely all be pretty weakened or KOd. I don't need a whole team full of utility, and I do need something that can just clean up the mess Riolu made afterwards. One great answer is a good Choice Scarfer. Primeape is a perfect Poke for picking off weakened opponents, revenge killing, and general scouting. The standard set is used because it offers the best power and coverage along with the coveted U-turn.
Ludicolo @ Life Orb
Trait: Swift Swim
EVs: 252 Spd / 252 SAtk / 4 HP
Modest Nature
IVs: 0 Atk
- Giga Drain
- Surf
- Rain Dance
- Ice Beam
Looking at the rest of the team, the last spot desperately needed to be filled with a special-attacking cleaner/breaker with elemental coverage, since the rest of the team is not really diverse. Ludicolo fills in the gaps nicely because the rest of the team doesn't have any Water, Grass, or Ice attacks. Also, Gardevoir can support Ludicolo. Even with just screens and no Memento, Ludicolo is almost guaranteed to set up the Rain safely and then begin cleaning. I chose Surf over Hydro Pump for solid, reliable damage. If all goes well, the opponents will be weakened to the point where a Modest, max SpA, Life Orb, Rain-boosted, STAB Surf will KO anyway.

Edit: Now I have 3 weak to Flying and 3 weak to Psychic...lol. It's better though.
