>>26821128Life Orb is bad on any Jirachi set, it's a Pokemon you don't want to be worn down too much regardless of its role.
Either way special Jirachi is pretty underwhelming compared to physical one. Iron Head + elemental punches provide solid coverage and plenty of opportunities to hax your opponent. You can even drop one elemental punch for Drain Punch if you need a lure for certain Dark types such as Bisharp. Goes well with Scarf, Band, Expert Belt or even Colbur Berry.
Another annoying set is SubToxic with Iron Head and Fire Punch as your attacking moves and Leftovers for passive recovery. Flinches + Toxic will obliterate even the sturdiest physical walls, as long as they can be poisoned.
