In general Jirachi doesn't run su much EVs investment alongside a LO and moves 4x supereffective on Tyranitar and is KO'ed in return by this pseudo-legendary even thanks to our very LO's recoil.
The key of this set are two moves. The fist one is Icy Wind, a useful move which provides some coverage alongside Spe control in order to neuter Scarf users and fast pokemon in general, thus providing useful team support. Icy Wind is useful on the switch to rectify Jirachi's "middling" speed tier.
Then, we have Drain Punch, a move which obliterates the remaining Tyranitar's HP left while regaining its health. I just want to underline the fact that Jirachi is immune to Sandstorm damage because is a Steel type.
0- SpA Life Orb Jirachi Icy Wind vs. 0 HP / 0 SpD Tyranitar in Sand: 31-38 (9 - 11.1%) -- possible 9HKO
252 Atk Life Orb Jirachi Drain Punch vs. 0 HP / 4 Def Tyranitar: 328-390 (96.1 - 114.3%) -- 81.3% chance to OHKO
252 Atk Tyranitar Crunch vs. 60 HP / 0 Def Jirachi: 270-318 (75.8 - 89.3%) -- guaranteed 2HKO
Or you can simply go straight with Drain Punch, but a little prior damage is needed to ensure the KO (one layer of hazards).
This lure has other notable uses outside this scenario i.e. punishing on the switch Bisharp, Heatran, Cobalion.
EVs spread: This spread allows Jirachi to eat a Crunch + eating a LO recoil without fainting.
