You and I Know
This is a Jirachi that I have been using since the Latias suspect test. It was effective then and it is still effective now, and since the closest set on-site is "Superachi" (which is pretty damn different), I figure this deserves its own set. Additionally, I know a number of other players who can attest to the effectiveness of this set.

<p>While Jirachi is typically seen either running Calm Mind or carrying Choice Scarf, this set is an excellent alternative which acts as both a mid-game wall breaker and a late-game sweeper. Be warned though - this is not a Pokemon which can be haphazardly thrown onto a team with the expectation of functioning well: it serves a very specific role and should only be used if your team is capable of supporting it.</p>
<p>Jirachi's main purpose is as a mid-game wall breaker. Like most mixed wall breakers, this Jirachi relies on excellent type coverage; however, unlike its companions Infernape and Salamence, Jirachi relies not on large damage output, but on surprise value. Expert Belt along with physical attacks will often cause the opponent to assume that Jirachi is holding a Choice Scarf and send in something like Skarmory, Swampert, or Salamence to take the opportunity to set up. Jirachi's oft overlooked 100 base Speed only makes it easier to create this illusion.</p>
<p>Even without bluffing Choice Scarf, however, the oddity of this set is often enough to work your opponent into a corner. If you manage to double-switch into something like Scizor, Swampert, or Salamence, it is unlikely that your opponent will switch out, and you can go for an easy OHKO (Salamence needs to take Stealth Rock damage, due to intimidate). Similarly, Jirachi is perfect for sending in after a double KO via Explosion or recoil damage.</p>
<p>Besides being a powerful wall breaker with its coverage and a useful late game sweeper with a 60% Flinch Rate attack and 100 base Speed, this Jirachi also serves as a useful check against a number of common OU threats. Most notable among these are Lucario and Latias: the former is outsped and takes a minimum of 78% damage from Fire Punch, a sure OHKO after a defense drop from Close Combat (and a possible OHKO after Life Orb and Stealth Rock Damage); the latter will always be 2HKOed by Ice Punch and will generally fail to 2HKO Jirachi.</p>
<p>There are two Pokemon to look out for when using this Jirachi. The first is Heatran, which 4x resists or is immune to every one of this sets attacks, and can easily OHKO Jirachi with Fire Blast. If your team demands it, Hidden Power Ground can be used over Grass Knot or Ice Punch in order to quickly deal with Heatran and Magnezone; however, this will open Jirachi up to even more threats which are more difficult to deal with than the generally predictable Heatran. The second Pokemon to look out for is Gyarados, which will not take much more than 30% from Grass Knot, and can easily set up with Dragon Dance. If you are more worried about Gyarados than Swampert, then you can exchange Grass Knot for Thunderbolt, though that will make Jirachi less effective against both Suicune and the Bulky Ground-type Pokemon. In reality, any combination of these moves can be effective; the key is knowing exactly what your team needs Jirachi to eliminate.</p>
