I must agree, HYU.
I think we should sopt and think for a second:
Why are we using Wynaut, apart from it being the focus, as in What role is Wynaut serving here ?
The two likely answers are:
1) To revenge scarfers, allowing a fast Pokemon to sweep without any hindrance
If this is so, then the perfect sweeper here would be Elekid. Elekid outspeeds everything unscarfed in Little Cup barring Voltorb and DIglett, but it is often stoppedin its track by Scarfers, who can easily OHKO it. With Wynaut, Elekid gains just the support to be able to sweep near mid game to late game once its counters are weakened.
Other options that do not require a turn to set up include Taillow and Teddiursa. Both of these have a massive attack stat and a STAB Facade, and can come in on a resisted move, like the omnipresent Missy's Shadow Ball. Infact, Teddiursa can come in on the Shadow Ball, activate its Quick Feet and OHKO Missy with Crunch. Taillow gets a powerful second STAB and STAB Priority, as well as U-Turn.
In case we are running WYnaut for this, then Wish support would definately be important, as Wynaut needs the extra HP Gain to be able to CounterCoat Scarfers one more time in case the opponent packs two of them. After that we can just build around our main sweepers, add something that weakens stuff midgame and have reliable checks to common threats
2) To provide a free set up turn for sweepers via Encore
This is the direction we are heading towards currently and IMO, upon reflection it doesnt require much Wish Support at all, as provided we can weaken stuff midgame and eliminate checks, our Set up Sweeper should be able to sweeeep through the remainder of the team.
There are tons of options here, however we must choose something that provides the best tradeoff between Power and Speed. RP Tar is a good example, reaching 25 attack and 26 speed, which even outspeeds many common scarfers such as Machop and Mankey, as well as some Houndour. RP Gligar loses a little power for added bulk. Agility Krabby reaches a phenomenal unboosted attack stat while getting 28 speed after one Agility. The downside is poor coverage and relying on CrabHammer for STAB. RP Cranidos is often overlooked due to weakness to priority, but with a team centered around it, it can be a force to be reckoned with, attaining 24 attack and 30 speed after one Rock Polish. Its phenomenal ability, Mold Breaker, also allows it to hit Bronzor and Misdreavus, rendering the opponent's "ground insurance" useless. DDtini is as formidable as ever and is certainly something to look into, although IMO people are too prepared for it nowadays for it to pull off a complete sweep. If I havent said anything here, its just because I have been looking at the less common options as they are the ones which people are not prepared for.

That was my take on the team building processes we can use to build our team
