Like the people above me, I honestly don't see the merits of a Claw Sharpen set just to boost accuracy. I see it as a waste of a turn, especially when the rain clock is ticking; Surf is better than Hydro Pump if it means you get an extra hit off. Like what Murkglow said, if you go physical you're MUCH better off using Swords Dance, as after 2 turns, it will have been beneficial.
