Where's the Riolu! Okay I don't play NU much, or I didn't but I always played against EBeast with a random shit team or various random shit teams. But I've started to like it because of some lesser used pokemon and this little guy in particular. The original set that I tested was the one below and what Molk started to test a little bit.
Riolu
Set: Copycat!
@ Eviolite
Trait: Prankster
EVs: 252 Atk / 4 Def / 252 HP
Adamant Nature (+Atk, -SpA)
- Copycat
- Roar
- Drain Punch
- Crunch
This set is fairly straight forward, Set-up hazards bring it in on a wall that you force out, don't get OHKO'd by and roar, Drain Punch or Crunch away, with the lack of spinners in this tier on numerous teams it's easy to keep the hazards up throughout the battle until a chance presents itself the few problems this set has is priority like Aqua Jet, Protect, Fake Out and Sucker Punch, but you have 5 other pokes to handle those and them coming in isn't reliable for the enemy so you just rack up more damage till they luck out.
After awhile I noticed I could do cool little synergies with slow u-turners, Volt Switches like Probobass and Eelektross and revenge some weakened threats or revenge things like Fraxure if it was locked into Outrage if I did a super frail build of
Set: Copycat!!!
@ Life Orb
Trait: Prankster
EVs: 252 Atk / 4 Def / 252 SpAtk
Brave Nature (+Atk, -Spe)
- Copycat
- Roar
- Drain Punch
- Crunch
With this set you can do rather gimmicky things which may not be really worth it in some people's opinions but getting some extra damage off with a priority u-turn/vswitch is just fun imo.
In the end I'm impressed the frail little guy that I started out using as a gimmick expecting to win nothing helped me achieve 38/13 on the PS ladder. there was a few times that I lost because it was my last poke but that happens to every pokemon and there's a lot of times it helped me out a lot.
