Jirachi suffers from Pokemon such as Heatran and Magnezone frequently in OU, and has nothing to deal with them outside of the rare Drain Punch. However, this set attempts to correct that by using Natural Gift, turning Apicot Berry into a 100 BP Ground type move that will most certainly OHKO Heatran and Magnezone (unless you're at like -6 and burned). The other two attacking moves consists of Jirachi's standard moves to paraflinch. The last slot can be tweaked to suit your Pokemon's needs, ranging from U-turn, to SR, Ice Punch, Fire Punch, Wish, Toxic, and more. However, U-turn is great for scouting switches, and SR is great to abuse the switches Jirachi can force.
EVs allow Jirachi to outspeed Timid Heatran, and the rest goes into Attack to hit has hard as possible, The remaining are used in HP to allow Jirachi to take hits better.
