That's an awesome set Hannah ^-^ Really cool use of sheddy, versus standard SD/X-scissor/Priority/Status or second priority.
A set I thought of for Smeargle: Suicide Bomber Smeargle @ Focus Sash Trait: Own Tempo Nature: Sassy (+SDef -Spd) or Timid (+Spd -Atk) EV: 252 HP, 128 Def, 128 SDef or 252 HP, 4 Def, 252 Spd IV: 0 Atk, 0 Spd (if using Trick Room. Spore Trick Room/Gravity Magic Coat/Taunt/U-Turn/Stealth Rock Memento/Healing Wish Designed to set up either Trick Room or Gravity for a team that uses said strategy. Spore puts the opponent to sleep, so the worst this set does is put something out of commission. Second slot is for a support move. Trick Room and Gravity both have their merits, so go with whichever one appeals to your team. Magic Coat reflects back Taunt, hazards, Roar and Whirlwind. Taunt achieves a similar effect, and can be used to render most walls set up fodder for a teammate. U-Turn lets Smeargle scout switch ins and grab momentum, as well as bring a field effect abusing teammate in cleanly. The last move is for when you don't need Smeargle anymore. Memento lets a teammate set up; Healing Wish can give an injured sweeper a second chance. Use nature and set up depending on which support move you went for.
I know this is pretty late, but since I've started using it again, and I feel like it has a slim chance of getting buffed next generation, here it is: The Most Underrated Chlorophyll Sweeper Whimsicott @ Life Orb Trait: Chlorophyll EVs:252 HP / 4 Def / 252 SAtk Modest Nature - Growth - Giga Drain - Hidden Power (Fire) - Shadow Ball It may seem kind of gimmicky, but I've gotten fairly good results with it, getting to as far as #7 on the ladder with it on my sun team. First off, it out-speeds most of the tier without any investment in Speed, barring +2 Terrakion, and Timid Venusaur, and max Speed Sawsbuck. This lets it run max HP, and with that, is a bit bulkier than 4 HP Venusaur. The main draw is the surprise factor. It's great at baiting in and killing things like Scizor and Ferrothorn, and there are plenty of Pokemon that love to have those things KO'd. Other things it can surprise and KO/get off crippling damage on are Pokes like Keldeo (switch into a Sacred Sword and take around 50%, then Giga Drain for 90% damage and take another. Out of all the Chlorophyll users, I feel like Whimsicott has the easiest time setting up, as it usually causes switches fearing SubSeed. After a Growth, the opponent usually has these 'mons on the field if they switched: Grass-types that can get KOd by +2 HP Fire, VoltTurn users like Rotom-W/Scizor which get destroyed, and Magic Bounce users, which get KOd by Shadow Ball. Sure it gets walled by Heatran, Dragonite, and Hydreigon, but with a solid team (especially with hazards) around it, offensive Whimsicott can sweep, or at least punch a pretty severe hole into opposing teams by killing off things like Scizor and Ferro. Here's one for example. There's a more in-depth look at what Whimsicott can do in there, with a whole bunch of calcs showing off the Surprise Factor, Sweeping Potential, and Bulk of this set. I also want to add that there's a small chance that Whimsicott could be retconned to be a Fairy-type, as it fits the mold pretty well (it's pretty clearly the Jigglepuff archetype of 5th gen). If that happens, then I expect offensive Whimsicott to be a major player next gen (at least for me).
A set I call Double Tap Rotom-W @ Leftovers Nature: Modest (+SAtk -Atk) Trait: Levitate EV: 252 HP, 252 SAtk, 4 SDef Thunder Wave/Discharge Will-O-Wisp Hydro Pump Volt Switch Designed to spread status. Being Water type, Fire and Ground types pretty much never switch into it. Therefore it can spread both Thunder Wave and Will-O-Wisp equally well. Thunder Wave guarantees paralysis - however, Discharge works through Taunt. Will-O-Wisp wrecks any physical attacker. Hydro Pump is the main STAB, and still does respectable damage to anything not resisting it that isn't a special wall. Volt Switch is useful for scouting. EVs maximise power and bulk.
