Check And Mate
Bisharp@Muscle Band/Focus Sash
Adamant nature
Defiant
252 Attack/252 Speed/4 HP
~Knock Off
~Iron Head
~Brick Break
~Rock Polish
Bisharp is just really, really cool. Knock Off is your main STAB move, it does excellent damage to anything that's got an item (which is basically everything). Iron Head is for additional STAB, and also to deal with those pesky Fairy-types which would otherwise wall this. Brick Break is for additional coverage, and also ensures that Reflect is not a problem. Finally, Rock Polish deals with Bisharp's Speed.
Item is for boosting Bisharp's Attack or letting it survive a setup turn, whichever you deem more necessary. Ability is the best it gets.
A Sucker For Chess Puns
Bisharp@Leftovers
Adamant nature
Defiant
252 Attack/252 Speed/4 HP
~Sucker Punch
~Iron Head
~Swords Dance
~Stealth Rock
This one's less about outright sweeping. Stealth Rock, well, we're all familiar with that one by now. Swords Dance boosts Bisharp's already serviceable Attack stat to godlike levels. Iron Head is STAB, and Sucker Punch is STAB and priority, helps make up for the lack of a speed-boosting move.
Item is for helping to keep Bisharp alive. Ability, again, is the best it gets. Helps with the Attack stat.
Metal Burstsharp
Bisharp@Focus Sash
Lonely nature
Inner Focus
252 Attack/252 HP
~Metal Burst
~Sucker Punch
~Quick Guard
~Pursuit
This one is out-and-out gimmicky. Metal Burst is the main move here- an opponent deals a heavy blow, activates the Focus Sash, and then Metal Burst turns it back on them for 1.5x the damage it dealt. Beautiful. Sucker Punch is to deal a little more damage before you then get KO'd. Quick Guard and Pursuit are mainly filler, but they do allow you to do something should you predict a priority move or a switch.
Item is for helping to keep Bisharp alive so it can do a Metal Burst. Ability prevents an untimely flinch interfering with Metal Burst, since you only get one shot at it.
Other options:
*Bisharp can run Low Kick over Brick Break to deal more damage to the heavier foes, and considering it's mostly Steel-types this move is for, it's not that bad an option. Steel-types tend to be heavy, after all.
*Foul Play sounds like an attractive option, but for that, you'd want an opponent with higher Attack than Bisharp, the likes of which are in rather short supply.
*If Rock Polish doesn't catch your eye, then maybe Thunder Wave is more your style. Rock Polish only requires one turn of setup, though.
Abilities:
*Defiant: Whenever Bisharp's stats are lowered, its Attack goes up two stages. Self-inflicted stat drops won't activate this. A popular way to combat Intimidate, which easily makes it Bisharp's best Ability.
*Inner Focus: Bisharp can't flinch. Useful when paired with Metal Burst, but otherwise, stick with Defiant..
*Pressure: Bisharp's Hidden Ability. When a move is used against Bisharp, it loses 2 PP instead of 1. Yeah... stick with Defiant. Bisharp doesn't have the bulk to pull this one off.
Partners:
You can't go wrong with Smashpassing. Or really, any Baton Passer with a Speed-increasing move. Hell, even Sticky Web support is useful. And maybe Rapid Spin to keep the Sticky Web off your end (though it would activate Defiant...).
Counters:
Fighting moves. Bisharp has decent Defense, but it doesn't matter much to something whose type combination lets it die to Rock Smash. As such, beware of priority moves- Mach Punch and Vacuum Wave in particular.
Opinion:
Cool. Just, cool. There's no other word for it.
Prediction for next week:
Slurpuff.
