1) Search through your boxes for a Pokemon with the 30 IV in whatever stat you need for the hidden power
2) Check that Pokemon with the IV checker. If he says the stat is fantastic, it's a 30.
3) Chain the IV using Power Items to whatever Pokemon you want.
4) Breed as per normal. If you ever want to check for sure whether the Pokemon passed down the 30 IV when you start using Destiny Knot + Everstone, use the battle test in lumiose citty for an instant IV battle.
