Shoutouts my buddy
daftmau5 for being part of the e-belt jirachi club since day one and innovating the nichze moonblast
I find expert belt jirachi to be a great asset for offense in the current meta game. It lures in what you'd lure in with many other lures/trappers that many people would come to scout for/ play too unpredictably/safely/aggressively for you to catch the Pokemon you're trying to trap.
Jirachi @ Expert Belt
Ability: Serene Grace
Shiny: Yes
EVs: 92 HP / 252 SpA / 164 Spe| 4 HP / 252 SpA / 252 Spe
Mild/Hasty Nature
- Icy Wind
- Hidden Power [Fire]
- Iron Head
- Moonblast/Thunderbolt
The first spread forgoes power over speed, doing more damage, and clinching ohkos on certain pokemon the hasty set fails to, while the hasty set outspeeds other neutral base 100s, hitting Pokemon like zard y after rocks, unexpectedly killing it off when they usually think rachi is a chance to roost(body slam para chance aside) I prefer the faster set myself.
This set lures in and takes big chunks out of common switchins like:
252 SpA Expert Belt Jirachi Thunderbolt vs. 252 HP / 4 SpD Skarmory: 262-310 (78.4 - 92.8%) -- guaranteed 2HKO after Leftovers recovery
252 SpA Expert Belt Jirachi Hidden Power Fire vs. 252 HP / 168 SpD Ferrothorn: 202-240 (57.3 - 68.1%) -- guaranteed 2HKO after Leftovers recovery
252 SpA Expert Belt Jirachi Hidden Power Fire vs. 248 HP / 176 SpD Mega Scizor: 221-264 (64.4 - 76.9%) -- guaranteed 2HKO
252 SpA Expert Belt Jirachi Moonblast vs. 252 HP / 0 SpD Mega Sableye: 185-218 (60.8 - 71.7%) -- guaranteed 2HKO
252 SpA Expert Belt Jirachi Thunderbolt vs. 252 HP / 172 SpD Mega Slowbro: 194-230 (49.2 - 58.3%) -- 98% chance to 2HKO
252 SpA Expert Belt Jirachi Moonblast vs. 0 HP / 0 SpD Keldeo: 228-269 (70.5 - 83.2%) -- guaranteed 2HKO
252 SpA Expert Belt Jirachi Hidden Power Fire vs. 4 HP / 0 SpD Bisharp: 175-209 (64.3 - 76.8%) -- guaranteed 2HKO(attempt if bisharp gets low, as it by nature gets worn quite quickly. Chances are they won't sucker you if they're unsure of your set.)
252 SpA Expert Belt Jirachi Icy Wind vs. 0 HP / 0 SpD Landorus-T: 293-346 (91.8 - 108.4%) -- 43.8% chance to OHKO(you outspeed in the next turn)
of course you can run the mild set for higher damage output, it's preference really.
E-belt rachi is a strong lure, giving under-loved pokemon the chance they need to shine in this metagame. So far i've used it with mega gallade and beedrill, and it's been successful in removing checks and counters for both, and i'm sure it has other uses i haven't found yet.
