Familiarity Breeds Strategy! (Japanese: ライバル決戦！サトシ対シンジ！！ Rival Decisive Battle! VS !!) is the 186th episode of Pokémon the Series: Diamond and Pearl, and the 652nd episode of the Pokémon animated series. It first aired in Japan on August 5, 2010 and in the United States on December 18, 2010.
==Blurb==
The first quarterfinal battle of the Sinnoh League at Lily Of The Valley Island has Ash pitted against his rival Paul. This round is a full battle, with each side using a full party of six Pokémon. As Ash switches out his first three Pokémon—Pikachu, Infernape, and Staraptor—there’s something quite familiar about it to Paul. In fact, Ash appears to be using the same Pokémon team he used in their first full battle at Lake Acuity! Paul begins the battle with Aggron, then Gastrodon, and brings his Drapion out after the first two are quickly defeated.
Watching the battle on television, Paul’s brother Reggie notices that Paul is well aware of Ash’s strategies. Reggie is convinced that Paul allowed Ash to take the first two wins as part of his overall plan!
After Ash switches Staraptor out for Buizel, Drapion catches Buizel in its pincer tail! We leave the scene with Ash screaming at Buizel to “get out of there!”—and as the action gets more and more intense, we have no choice but to wonder how this incredible match will ultimately play out!
==Plot==
Determined to settle their long-standing rivalry once and for all, and Paul are set to face off in the first quarterfinals showdown of the Lily of the Valley Conference. Ash decides to begin with , and Paul orders out his first Pokémon, .
Prior to the match, Ash gets some last-minute with , who recently returned from its training session with Air Battle Master McCann. Gliscor practices in a session against Dawn's Mamoswine while watches on. Reflecting on his Full Battle against Paul at Lake Acuity, Ash remarks that Paul takes everything he has learned in battle and uses it to his advantage. Barry claims Ash does the same thing, but Ash replies that he still needs to look at everything he has been through while on his . Barry asks if he figured it out, but Ash says that he will just have to wait until the battle, much to Barry's frustration.
Meanwhile, Paul talks to his older brother Reggie via videophone about his upcoming battle with Ash. Dawn enters the Pokémon Center lobby looking for her friends, but she quickly ducks out of sight. Reggie regrets not being able to be there, but Paul understands that he cannot just drop his responsibilities. Reggie asks Paul if he wants to reconsider which Pokémon he'll be taking into the match, but Paul confirms he's satisfied with his lineup. Reggie notes how glad he is that Paul met Ash, as he knows that no other trainer has influenced his brother as much. Reggie then advises Paul to not underestimate Ash but to power through the battle and win. Paul thanks Reggie and ends the call, then discovers Dawn eavesdropping. As they walk outside, Paul confesses his main problem with Ash - his talk about bringing out a Pokémon's inner strength and how any Pokémon has the potential to be strong reminds him a lot of Reggie. Dawn points out to Paul that Ash and Reggie are different people. Everyone soon meets outside. Paul then prepares to leave, but abruptly stops when Dawn utters 's quote back at Amity Square, "When every life meets another life, something will be born". She is left wondering what that "something" might be but hopes the quarterfinals might shed some light. Paul tells Ash that he will see him on the battlefield to which Ash agrees.
Returning to the present, Paul begins by having Aggron use , and Ash has Pikachu counter with . Though the two moves cancel each other out. Paul then tells Aggron to use , a high-frequency that lowers Pikachu’s special defense. Ash instructs Pikachu to use to stop Aggron's attack, and Pikachu manages to pull it off, stopping Aggron as well as causing a little damage. Pikachu then uses , speeding towards Aggron. Paul counters with Aggron's , hitting Pikachu and sending him flying, rolling back onto his feet. Ash knows Pikachu is struggling and decides to substitute him with . Cynthia recognizes Infernape as the she once battled, while Team Rocket is excited to see Infernape battle, having had a soft spot for him since the Hearthome City Tag Battle Competition. Paul tells Aggron to use while Ash tells Infernape to counter with . The two powerful and dangerous attacks collide, and Infernape suffers from the recoil. However, Aggron has the Ability, which cancels out recoil damage. Luckily for Ash, Aggron ends up with a from Infernape's Flare Blitz. Ash then instructs Infernape to use , and Paul orders Aggron to use Flash Cannon, but Infernape lands the fast Mach Punch before Aggron can fire, sending it flying into the wall behind Paul and crushing the surface on impact. The dust clears to reveal Aggron unable to battle, giving Ash the lead.
Paul recalls Aggron and sends out . Ash, knowing a and like Gastrodon has a huge advantage over a , calls Infernape back and sends out . Gastrodon begins with and Staraptor uses and connects. Surprisingly, Gastrodon continues using Muddy Water, circling its head above its body to create a Counter Shield, a technique adapted from Ash, and clips Staraptor. Ash instructs Staraptor to dive down and use Aerial Ace, though Gastrodon counterattacks with , pinning Staraptor to the field with its soft body. Gastrodon uses aimed at the sky, and the move picks up speed as it descends. Ash realizes that Gastrodon will jump away at the last second, giving no time for Staraptor to dodge it. Just when all seems lost, Ash has Staraptor use on the battlefield, lifting the up, which knocks Gastrodon off and it escapes the Water Pulse. Paul orders Gastrodon to use , bringing the in-flight Staraptor to a screeching halt and crashing onto the field. Ash decides that he will have to recall Staraptor for later and change his strategy.
Ash sends out . At this point, Paul points out that what Ash is doing is too predictable now. He knows Ash is just trying to get rid of all the frustration his Pokémon felt from that loss back at Lake Acuity into his advantage here which is why he brought them all back for this battle. Ash states he is correct and that this is what all of his Pokémon want. Gastrodon uses Ice Beam again and Buizel approaches with , turning it into Ice Aqua Jet. The combination narrowly misses its mark as Gastrodon launches into the air and then goes for a Body Slam. Ash thinks quickly and instructs Buizel to meet the attack with , causing Gastrodon to faint.
Ash settles himself, adjusting his cap, and knows that the hard part of the battle has only just begun. At his home in Veilstone City, Reggie watches the broadcast, wondering if Ash has figured out that Paul had planned to sacrifice Aggron and Gastrodon in the beginning all along, and knows that, if not, he will be in trouble. Meanwhile, Paul sends out and has it use , but Buizel cancels the attack out with a Counter Shield. Drapion then uses , which Buizel dodges by sliding behind Drapion. Buizel then launches a , but Drapion blocks the attack with its tail, before using said tail to reach out and grab Buizel. Drapion then 180s its torso to face the trapped Buizel and prepares to attack. Ash realizes that Drapion has no blind spots, and calls for Buizel to escape Drapion's grasp.
