I know I'm quite late, but I felt I should bring this up regardless:
You may want to change Sheer Force for another ability, or replace Crabhammer with Liquidation, as all of Krabby's attacking moves are unaffected by Sheer Force (Knock Off being able to remove items, as well as raised crit ratios aren't affected by Sheer Force). Additionally, it's typically a bad idea to run two setup moves & Life Orb, as you'll likely be at low health by the time you setup Swords Dance and Agility, and you'll even take damage from Life Orb too.
