Have you ever sat down and thought, "Gee, I wish my Simple pokemon didn't have to worry about improofing," or "I wish I had some extra speed control on this team?" Well you're in luck, because Today I'll be breaking down exactly how to solve both of those issues with two simple words.
Why use Booster Energy? It, when combined with Protosynthesis or Quark Drive, allows your pokemon to both beat their own Imposter with the correct EVing, and also give you some emergency speed control for their sweeper at +1, or maybe even 2. Now, you may be wondering, what Booster Energy pokemon are there that you could possibly use in such a high-powered meta like PokeBH? Well, dear citizen reading this post on www.smogon.com/forums/threads/om-mashup-megathread.3711916, I'm glad you asked this, for I have compiled a list of pokemon that can use this, and even created sets and EVed them to beat their own Imposter, for your viewing and usage enjoyment.
First off, we have Flutter Mane, a pokemon whose high Special Attack and Speed comboes with its threatening STAB combo of Ghost/Fairy to create a lethal offensive pokemon, and now, it can't even be stopped by Imposter. The combination of Astral Barrage and Moonblast 2HKOs almost the entire tier, with Pain Split making it incredibly hard for pink blobs like:Audino-Mega, Chansey, or Blissey to stop you. The provided spread always OHKOs Eviolite Imposter from full after a Nasty Plot with Astral Barrage, Moongeist Beam can't quite OHKO Imposter, so I would advise against its use.
Next, we have the Big Gouger, who I think might be getting slept on a little because of Reshiram. Reshiram might be the better sun pick, but this Gouging Fire set is incredibly dangerous after just a single Swords Dance. Glaive Rush is a great STAB, and while normally the Fire STAB of choice is V-Create, Simple and Booster Energy both anti-synergize with it, so instead I've opted for Pyro Ball. Sunsteel Strike threatens any Fairies or FC pokemon that would try to slow you down, and because of your natural Fire typing, you're even able to spam contact moves like Sunsteel Strike or Glaive Rush without being scared of Bulwark.
Boulder has a rather unique set of traits that I think makes it a good user of Simple+Booster Energy. It's very fast, it has SE STAB on Toxapex and Ho-Oh, and it has STAB that punishes Bulwark usage heavily. You could theoretically swap out Headlong Rush for Precipice Blades to counter Bulwark Steels if you feel lucky, or Gigaton Hammer to allow you to run a lot more EVs in Defense(instead of having to use 0 EV/19 IV Hasty, you could use 96 EV/31 IV Jolly), but then Imposters could switch out on the Gigaton, sack a different pokemon to it, and kill you with Gigaton in return, so I woudn't personally recommend it. I wouldn't recommend using Sunsteel Strike over Headlong Rush either, as it cannot quite OHKO Imposter.
Bundle sports probably the most unique spread I've made for any of these pokemon, but it hits a few critical benchmarks. Modest 212 Special Attack is stronger than Timid 252 on Iron Bundle, while also still allowing for Booster Energy to boost Speed. This increased Special Attack also allows you to run more Special Defense EVs (176 vs 124) while still always OHKOing Imposter with Electro Drift. Freeze-Dry and Ice Beam are both very solid Ice STABs for Bundle, and Steam Eruption is a good secondary STAB.
Not too much to say about this one, it's a fast Booster mon weak to Electro Drift, so Improofing is pretty easy, don't know if I'd use it vs any of the Scales mons in the meta, but I think it has a chance to be able to do some interesting things.
Another fairly simple set, STAB Flower Trick hits like a truck, Attack Order makes Improofing simple, Triple Arrows slam Steels. You could very easily swap out Flower Trick for a Psychic STAB like Psychic Fangs or Psyblade if you need to hit Toxapex.
This is the first of two pokemon that I've cooked two different sets for, but unlike the one coming up, both of the two sets are fairly similar. Malignant Chain+Fire STAB(can be Torch Song, Armor Cannon, Blue Flare, etc)+Improofing Move+NPlot. The difference comes primarily in the EVs necessary for the two different Improofing Moves(Psystrike and Earth Power). The other main difference is that Psystrike is slightly better into blobs like Blissey/Chansey, and Earth Power is better into Mega Tyranitar, so just pick whichever suits your team best.
Another good user of Simple+Booster Energy, Iron Treads has STAB SE on itself for easy Improofing, and also has STAB Sunsteel Strike, making it a super threatening pokemon, especially as the pokemon you'd ordinarily use for checking Ground/Steel moves in PokeBH, Ho-Oh, gets eviscerated by +4 Mighty Cleave.
The second pokemon that I've cooked up two sets for, and probably the most flexible pokemon on this list, Iron Valiant is in a very unique position, where as long as it runs Fairy STAB for self-proofing, it can really use whatever two coverage moves it wants. Glacial Lance for Gliscor, Electro Drift for Ho-Oh/Toxapex, Precipice Blades for Mega Steelix, you get the idea. It can easily pick apart just about any team with the right coverage moves. Very scary pokemon, don't sleep on this.
A pokemon that I'm not as sure about, Raging Bolt feels like just worse Miraidon/Ampharos-Mega, but it might be able to leverage its 409 speed tier after Booster and Simple Nasty Plot to do something. Fairly basic moveset, could probably be experimented with more.
Another Dragon, this time a bit faster and stronger than Gouging, but a lot worse into Fairies, Roaring Moon can threaten to seriously mess with most teams with Glaive Rush/Knock Off/Sunsteel Strike, and can also switch out Knock Off for Wicked Blow if you want to sacrifice utility for raw damage output. Another scary pokemon, does feel a little awkward to set up at the moment, and hates Bulwark 50/50s, but definitely keep an eye on this mon.
A pokemon I haven't experimented with much, inspired by
Slothy0wl's usage of it on a rain team a couple weeks back, Sandy Shocks is a fairly simple pokemon for my purposes. Fast, STAB Electro Drift, SE STAB on itself for easy Improofing, and then a flex slot to do whatever it wants with. Could do with some tinkering, and feels a little frail, but isn't a bad pokemon by any means.

While it's not much of a problem in base ABC, Pokémon like Salamence, Hisuian Braviary, Primarina, and Blastoise could now run -ate or Liquid Voice, giving them an extremely powerful STAB move.
Triple Arrows with Serene Grace is dumb, especially since the abusers like Paldean Tauros forms and Terrakion now have access to Tidy Up.
We don't view either Zamazenta form as a big problem, as both are legal in AAA (and the former is legal in ABC) and don't get any moves that make them broken.
