Ambipom @ Normal Jewel

4 HP/252 Atk/252 Spe

-Fake Out/U-Turn/Ankle Sweep/Double Hit/Fling/Whatever
Fake Out -> Covet or just Covet and nuke something with your 202.5BP attack while simultaneously stealing their item. If you get a Flame or Toxic Orb or something heavy you can fling it later, or you can just fling the item you get so you can Covet steal another later. Doesn't really matter what is in the last slots though, really it's all about the Covet+Normal Jewel or the NJ Fakeout -> Covet. If you think their poke will trick or switcharoo you a scarf or burn orb you can simply covet and let them waste a turn unless they're faster.
Gardevoir @ Choice Scarf
Modest
Trace
4 HP/252 S.Atk/252 Spe OR 4 HP/ 252 Def/ 252 S.Atk
-Will-o-Wisp/Hidden Power Fire/Hidden Power Dragon
-Focus Blast
-Psychic
-Thunderbolt
Switch into Doryuzuu or a swiftswimmer and kill them. You can outspeed with a scarf at 0 Spe EVs but then outside of tracing swift swim/sand throw your Gardevoir is really slow (even with Scarf) and kinda useless. Also you won't outspeed a +1 Kingdra with no speed EVs so I recommend full speed EVs. If you trace a Chlorophyll user you can use Psychic (Venusaur/Victreebel) or HP Fire (if you choose it over HP Dragon/WoW).
You can also try and switch into a Sun Power/Sand Power user and attempt to seriously hurt them or whatever switches in (Max Speed EVs needed if you're not going to trace swift swim/sand throw).
Focus Blast OHKOs Dory but Hidden Power Fire doesn't. Unfortunately she can't really beat Kingdra if it's at +1/+1. But she could get a burn in and maybe a little damage to help someone else take it out as she outspeeds +1/+1 Kingdra with full speed EVs.
If it's any weather abuser except Kingdra then she can probably kill it. Although for Dory you have to pray that FB doesn't miss.
If you could pass her some Calm Minds or Nasty Plots just as they switch in or just as they SD/DD/Growth then she can definitely win.
It sucks that her base speed isn't just a tad higher, then she could outspeed those OU weather abusers and win without the choice scarf.
Edit: You can also switch in on Speed Boost Blaziken as it protects and kill it with Psychic, although if they don't protect you might be in trouble.
