I've always loved the idea of RU. It lets the Pokemon that are weaker or not used very much shine, without being unacceptably weak and make for boring battles. If we didn't have the lower tiers, only about 5/6 of all the pokemon wouldn't even be used at all. I myself personally like Furret. So, post away, and feel free to point out any typos or things I forgot to change (sorry if I say UU instead of RU I just did an article about UU somewhere)!
Furret (M)
Item: Choice Band
Ability: Frisk
Nature: Jolly (+ Spe - Sp. Att)
Moveset:
~ Trick
~ Return
~ Brick Break
~ U-turn
Evs: 4 HP / 252 Atk / 252 Spe
First of all, PLEASE NOTE:
Furret isn't necessarily my lead , you can switch before the start of the battle in the preview. I usually don't put my lead at the front, as then people will know its a lead . I just decided to show him first. I usually start with Alakazam or Claydol.
Furret can be an amazing Pokemon. Choice Band raises the attack, making Furret's somewhat average attack stat more usable, and taking down opponent stalls easily, trapping them into using one move. When i send it in, Frisk will tell me if my opponent has an item i don't want, (such as another choice item or a Toxic Orb.), in which case I'll Simply use U-Turn. If if has an item I'm okay with or do want, I'll use Trick, then sweep the hell out of their team.
As for the moves, Return is a nice STAB move that can hit hard. (I'm pretty sure at full happiness it has a base power of 112. With STAB, that's 168). Brick Break is a nice coverage move that hits Normal, Ice, and those bulky Rock types, hard. U-turn, as I said before, is for when i come in and my opponent has an item i don't want, or i just need to hit a Dark or Psychic type.
Tangrowth (F)
Evs: 252 Def/252 HP/4 Att
Item: Leftovers
Nature: Impish (+Def, - Sp. Att)
Ability: Regenerator
Moves:
~Sleep Powder
~Power Whip
~Earthquake
~Leech Seed
Leftovers is obvious. So is Impish. Regenerator is probably the best ability for a tank or wall to have. Have low health? Then just switch out, and around 1/3 or it is healed. Awesome.
Sleep Powder is great to help me where down my opponents health. Power Whip is an awesome STAB move, with a base power of 180. EArhtquake is also a powerful move to use against Fire types. Leech seed lets Tangrowth regenerate even more health.
Tangrowth is simply beast. He is pretty much the best wall I can ask for. Sometimes, my teams can be easily defeated by a physical sweeper. Not here. The pumped up sweepers that will completely crush the rest of my team, all in one, will barely take 20 HP from good old Tangrowth. He's also good if my team needs an opponent to be put to sleep, so we can chip away (no, not the move) their health.
Rampardos (M)
Item: Choice Scarf
Trait: Mold Breaker
EVs: 12 HP / 252 Att / 244 Spd
Jolly Nature (+Spe, -Sp Att)
~ Rock Slide
~ Earthquake
~ Fire Punch
~ Pursuit
Having the highest attack is RU, he can be pretty beastly. The problem is, his speed sucks, but that is aided by Choice Scarf, making his speed a usable 323. Mold Breaker is great for hitting those pesky Levitate Pokemon with Earthquake. Jolly is obviously the best choice, as you could raise his attack, but that would render his speed un-usable.
Rock Slide is better than Stone edge in this case, because one stone edge miss could be fatal, as his frail defenses will get him there. It has an okay power, but with this attack stat, it's still a pretty beastly move. Earthquake is has amazing power and accuracy, not to mention can now hit Pokemon with Levitate, making it a amazing choice. Fire Punch can be used for grass types who are resistant to his other moves, and not a bad power either. With pursuit he can hit Ghost types, and anybody trying top switch out, hard.
Again, not much of a strategy, besides hitting switching Pokemon with pursuit, and using raw power to sweep.
Claydol
Item: Leftovers
Nature: Relaxed
Moveset:
~ Stealth Rock
~ Rapid Spin
~ Earthquake
~ Ice Beam
Evs: 252 HP / 252 Def / 4 SpD
Claydol is a unique psychic type, with it's bulk letting it both set up, and take out entry hazards. Leftovers is obviously a good choice for a Tank.
Stealth rock can be used if Steelix is taken out. Rapid Spin is great, taking extra damage of my my team, but also essential for me to use regice, as it would otherwise be greatly damaged by Stealth Rocks. Earquake can hit most most Pokemon hard, and has a usable accuracy for a move with 100 base power. As for Ice Beam, i could have chosen Toxic, but it wouldn't be good to have only one attacking move, preventing me from doing much damage to Flying types, and everything resistant to Ground.
Alakazam (M)
Item: Focus Sash
Ability: Magic Guard
Nature: Timid (+Spe - Att)
Moveset:
~ Taunt
~ Psychic
~ Focus Blast
~ Energy Ball
Evs: 4 HP / 252 SpA / 252 Spe
Alakazam is amazingly powerful. I'm surprised he isn't in UU. He can also prevent set up sweeps, so i usually start with him. Focus sah is obviously aweome on him, as it gives him a second chance to sweep if he is hit.
Taunt, as I said, is to prevent set up sweeps, and also prevent any stat lowering move on my part (or stat raising move on their part). Psysic is an obvious STAB move, hitting everything but Dark with a powerful punch. Focus Blast, although it has low accuracy, is needed when either i am facing a Pokemon with incredible special bulk, or i am facing a dark type. Signal beam is also a pretty powerful move, hitting dark types and other Psychics when i cant afford to miss.
Regice
Item: Leftovers
Nature: Bold
Moveset:
~ Toxic
~ Ice Beam
~ Thunderbolt
~ Seismic Toss
Evs: 252 HP / 252 Sp. Def / 4 Def
Regice is the best special wall in RU, and also might be able to survive a physical hit or two, which is helpful. Leftovers can really help it regenerate a lot of health over time. I use bold so that it might be able to survive a physical hit.
Toxic is choice for stalling. ice beam has a great accuracy, and made more powerful with STAB. Thunderbolt is also a good move, making use of it's good special attack stat. Seismic toss is used for consistency, or agaisnt other special walls.
