DO NOT USE FOCUS PUNCH IF YOU CAN HELP IT!!! At full-power, Reversal is stronger than Focus Punch and a lot more reliable. Plus with 31 Attack IVs and a lot of Attack EVs, you can OHKO just about anything. Isn't Reversal better? Just make sure you get rid of any Sandstorms; put a Sunny Day user on the same team as the Pokemon using Reversal.
