This was a fun team to build. All of the Pokemon can be used as wincons, as requested, but some of them are more likely to wincon than others. SD Drilbur being a wincon is a bit iffy, but I think the team needs Stealth Rock enough to warrant it. Rapid Spin isn't needed because Vullaby/Gastly/Pawniard all dump on webs. Gastly doesn't have a set-up move but is a good wincon against slower teams without Pursuit. Gastly/Vullaby/Pawniard are all more likely to be breakers, though. Adamant Pawniard is used because Jolly isn't really needed if you aren't Brick Break. Most of the sets are pretty self-explanatory; they're all there to win against the right team, except possibly Drilbur.

These wincons were chosen so that the team doesn't just lose to opposing wincons. Timburr checks Omanyte, and Omanyte can only really set up on pre-NP Vullaby. Pawniard and Timburr check Shellder. Timburr checks Carvanha and Pawniard. Pawniard and Omanyte check birds. Omanyte checks Ponyta. Drilbur checks Magnemite.

The team's biggest weakness is Corphish, which you just have to make sure doesn't set up. Most of the team can pressure it except for Drilbur, though; just don't be afraid of sacking something, but I probably don't need to mention that to Mr. 6-scarf berks. Fletchdig also threatens a lot of the team but is even easier to pressure.
