Well, Bisharp was denied OU and will be debuting in UU Beta this generation. Bisharp, however, will be able to fit into this metagame perfectly and you can bet I will be abusing it as much as I can before it eventually gets sent up.
First things first is that every team looking for perfect synergy will require a Dark or a Normal type. Only Dark resists Ghost. Another thing is that Bisharp no longer worries about getting wall by every Steel now Dark can it normally. Sucker Punch can run right through it hitting Scizor, Genesect, and Aegislash.
You might think that Aegislash could care less for Bisharp thanks to King's Sheild, but when Aegislash uses King's Shield on Bisharp, he won't lose any attack thanks to his ability Defiant. The same goes for when Bisharp lands on Sticky Web, but instead, his Attack goes up by 2.
Bisharp @ Leftovers / Life Orb
Ability: Defiant
EVs: 200 HP / 252 Atk / 56 Spe
Adamant Nature
- Swords Dance
- Iron Head
- Knock Off
- Sucker Punch
Fairly simple Pokemon who can fit on any team as a setup sweeper. Swords Dance makes Bish able to destroy anything that it won't resist his attacks. Iron Head now hits Fairy's and can cause flinch a healthy amount of the time as well as providing a strong STAB move. Knock Off got a huge buff this generation and Bisharp is one of the strongest users of it. It can also tack off an item from the opponent. Sucker Punch can land some faster hits as base 70 speed isn't too impressive.
The EVs give him enough bulk to avoid being 2HKO'd by weak Hidden Powers and fast enough to outspeed some Aegislash and Scizor sets.
You also have the choice of choosing between Leftovers and Life Orb. Leftovers will increase survivability while Life Orb will do the exact opposite, but still tack on a lot of damage.
Have fun with Bisharp, try to use him as much as possible in UU just in case it gets sent up OU!
