Doubles.
Many people like myself love creating new, unique strategies to utilize in the double battle metagame. I mean, there is an entire thread dedicated to it in the forums that has some really great strategies hidden between the pages.
After a long Pokemon hiatus, I jumped back in and realized that maybe the best offense is, in fact, a solid defensive strategy. Instead of presenting you with a new Trick Room, Gravity, or unique Weather team, my team adapts to the situation and works to combat enemy strategies. Keep in mind as you read this RMT that I play on PBR, so trainers can see the other person's roster before battle. It's been a while since my last RMT, so without further adieu...
Crobat@Sitrus Berry/Leftovers
-Inner Focus-
Jolly Nature
EVs: 252 HP / 252 Speed
-Taunt
-Screech
-Super Fang
-Quick Attack
Crobat is usually paired with Kangaskhan as a lead. Crobat's Inner Focus ability is extremely helpful when dealing with opposing Fake Out attacks on the first turn. With the ability to never flinch, Crobat can successfully Taunt teams that rely on setup strategies (Trick Room, Gravity, Non-Ability Weather Effects, etc...). Screech is there mostly for Kangaskhan, but also works well with Swampert, Golduck, and Bronzong. What's better than Helping Hand in doubles? A -2 to the opponent's defense that gives your partner an OHKO! Super Fang is a welcome addition that instantly reduces a target's life to half of its current HP and Quick Attack is there for sashes. Most people expect Crobat to lead with a weather effect or Hypnosis, so I go for the element of surprise here, while supporting the rest of my team. I'm struggling to assign an item to Crobat...I dislike overusing Leftovers, so Sitrus Berry is a more immediate option for recovery. Any suggestions are welcomed!
Kangaskhan@Lum Berry
-Scrappy-
Adamant Nature
EVs: 252 HP / 56 Atk / 200 Def
-Fake Out
-Counter
-Focus Punch/Return
-Sucker Punch/Earthquake
Kangaskhan has a lot more bulk than people give it credit for. With the given EVs, she can survive an array of physical attacks including MixApe's Close Combat, Tyranitar's Stone Edge, and most non-STABbed fighting attacks. Fake Out is bread and butter here - combined with Kanga's Scrappy ability, nothing resists it (unless Kangaskhan is hit by a speedier Fake Out the same turn). Focus Punch is deadly, but risky in double battles, so I'm considering Return or Earthquake in its place. Sucker Punch is viable against faster enemies and its damage is considerably higher when paired with a Screech from Crobat. Lum Berry is critical for stopping enemy status leads.
Golduck@Wide Lens
-Cloud Nine-
Mild Nature
EVs: 104 Atk / 252 Sp Atk / 152 Speed
-Cross Chop
-Hydro Pump
-Ice Beam
-Encore
Golduck gets a gold star for his ability, Cloud Nine, in the doubles metagame. SO many teams are based upon weather effects and he can temporarily disable them by simply switching in. Given, Golduck does not like taking hits, but with accurate prediction, he isn't too difficult to switch into battle. Cross Chop is for normal types and Tyranitar and Hydro Pump deals mega damage to unresistant enemies. Ice Beam is great for coverage and gets rid of Flygon, Salamence, and Jumpluff. Encore has become my favorite move on this set because Golduck has reasonable speed and can screw up teams even more. Keep in mind that Encore also disables the opponent's option to choose a target in doubles! Wide Lens really helps with Cross Chop's and Hydro Pump's mediocre accuracy and I've grown to like it. I once thought of using a fully Sp Atk / Speed EVed Golduck because Tyranitar loses its 1.5X Sp Def boost when Golduck switches in. Focus Blast deals more damage, but also limits his versatility. What do you think?
Rotom-H@Leftovers
-Levitate-
Bold Nature
EVs: 252 HP / 168 Def / 88 Speed
-Shadow Ball
-Thunderbolt
-Overheat
-Thunder Wave/Will-o-Wisp
Rotom was kind of a wild card for my team. His ability is welcomed by Swampert and Kangaskhan's Earthquake attacks and he provides a reasonable counter to Explosion-based teams alongside Bronzong. Shadow Ball and Thunderbolt are for STAB and Overheat adds a much-needed fire attack to my team. Thunder Wave helps out the team's average speed stats and Will-o-Wisp effectively cripples physical attackers. Rotom has the standard EV spread now, but I'm considering retraining it for a larger boost in Sp Atk. Unfortunately, PBR doesn't recognize Rotom's unique forms, so that was a bummer when I recently found out in an online match. :(
Bronzong@Light Clay
-Levitate-
Careful Nature
EVs: 252 HP / 128 Def / 128 Sp Def
-Reflect
-Light Screen
-Gyro Ball
-Explosion
I wanted a steel type on my team who could support effectively and Bronzong immediately came to mind. Double screens really boost the survivability of my team and Gyro Ball is effective against faster enemies. Explosion is an iffy move...I only use it in conjunction with Rotom-H or Swampert (when he uses Endure). Levitate definitely comes in handy with the oversupply of incoming and outgoing Earthquakes.
Swampert@Custap Berry
-Torrent-
Adamant Nature
EVs: 252 HP / 252 Atk
-Earthquake
-Waterfall
-Hammer Arm
-Endure
Swampert is a complete beast and provides a valuable electric-switch in for Crobat and Golduck. He doesn't have any speed EVs because he's not really a quick sweeper in the first place. Therefore, Hammer Arm doesn't really hurt him. Earthquake is great for STAB and Waterfall is my favorite move to use in conjunction with the Custap Berry. For example, if Swampert is bracing itself (Endure) for Bronzong's Explosion or a KO from an enemy, it will receive priority at the start of the next turn. He resists the oh-so-common Sandstorm and most opponents don't expect the berry, so they don't bother with priority moves. Waterfall becomes crazy powerful when Torrent is activated and even has a chance of flinching the opponent. I love Swampert.
There isn't an official Doubles Metagame 'Threat List' that I'm aware of because there aren't really any tiers when using PBR. If there is a threat list, please point me to it and I'm glad to post an analysis.
Comments and advice are appreciated.Let me know what you think!
