Wide Guard is one of those moves you really never need in the official games but Reborn loves its OP Doubles so much that it's super useful for setting up. Especuially since the AI isn't smart enough to not spam Rock Slides against it. Charlotte's team is mostly frail attackers so with enough boosts - Field, weather, held item - a powerful attack like Eruption can rip through her even with the Type resistance. I used a Drought Ninetales with Heat Wave and the Metronome held item on Typhlosion.

Flying is a pretty cool Monotype; since almost all Flying Types are dual Typed you get a pretty wide variety of Type combinations to choose from. My favorite combinations were Jumpluff's Grassy Field + Charizard's Heat Wave and Archeops' Rockslide + something with Mirror Move. Poor Decidueye tho, just gettinng dumped like that. How could you.

If you want to use the same six Pokémon for everything you should think about Doubles snyergy in your team as many of the hardest upcoming battles will be Doubles. Typhlosion for instance would appreciate a fast partner who could set up a Grassy Field or Sunny Day to Eruption your way through enemies. Since Eruption relies on HP Araquanid is actually also a great partner as it gets bot Sticky Web (as Edo already mentioned) as well as Wide Guard to protect Typhlosion from RockSlide and Earthquake. I used Eruption quite a lot during a Fire Monotype and it's very powerful when properly set up; you can even use it to sweep Charlotte.

The Plusle she throws out at the start is so weak that it should still work, unless it boosts itself literally every turn. I know I've set up on it before.

Braixen might be able to sweep by setting up to +6 with Howl and then Flame Charging everything. Just make sure not to die to Aftermath.

So a game containing only Fakemons? There's already a bunch of those around so it's definitely possible. I don't know anything about how to produce a fangame but you could always just go check how one of the existing ones handled it. Pokémon Sage is the first that comes to mind right now but there's others out there.

It also got them shunted to post-Agate Circus so I'd say they're disqualified as best 'Mons due to being unavailable for the majority of the game.

You can get a Trapinch by trading a Mothim to a guy in a house in Chrysolia forest (might have to teleport it there first from Spinel Town if you haven't already); Flygon isn't too well-suited for Serra's gym, but it's strong and has a great movepool. Also has Levitate, so immune to Ground. It's imo the best Pokémon you can get around this part of the game. You can also get an Eevee from a cave in Chrysolia Forest to evolve to any of its evolutions. Azurine Island has wild Yanma - Yanmega is one of the stronger Bug Types out there and Speed Boost is a handy Ability for many situations. Tanzan Mountain has wild Sandile - one of Krookodile's Abilities is Moxie and it has decent enough Speed to overtake a lot of enemies if you invest in it.

@repressible_operonDo you have some way to set up Sunny day and the helkd Item Metronome? If so you could try spamming increasingly powerful Heat Waves with your Charizard. Just gotta protect it from Darmanitan's Rock Slide. Route 4 has wild Bronzong - capture one with Heatproof as Ability and teach it Trick Room to turn the mostly speedy nature of Charlotte's team against her. The various Rock Types on Route 4 can also be used against her under Trick Room. The Move Relearner in Agate Circus can get you Rock Slide on your Steelix as well.

You can always check your level cap on your trainer card - the little squares where the Badges go show the your level caps until you get each Badge. If you need to grind and are out of trainers the deepest part of Below the Grand Staircase has wild Unown that can go pretty high in level while also being pretty easy to beat. The go to strategy for Shelly is to use a Pokémon with Fake Out to stop her Prankster Illumise from setting up Rain Dance (your Persian should have this, otherwise wild Espurr in the Aqua alleyway already have it in their movepool). A Fire Pokémon can then KO Illumise with a move that changes the Field to Burning. This also stops her Swift Swim Anorith from wreaking havoc on your team with Rock Slide.

Numel is available after Julia when it's raining. The spreadsheet says "Before Badge" so you probably got confused there. Sentret can be found in Obisidia Park - that's where you fought the Pulse Tangrowth.

Only way to change weather besides waiting it out is to either change the time/date on your computer or to download a mod that lets you set whatever weather you want. If you go east right above Julia's gym in Peridot you can go under the Opal Bridge. One of the buildings in Onyx Ward has a roof garden where wild Spearow can be found. Fearow is a pretty strong Flying Type at this point that should be a big help with Fern and the Gym.

Gen. 1 - Arcanine Gen. 2 - Lugia Gen. 3 - Sceptile Gen. 4 - Lucario Gen. 5 - Zoroark Gen. 6 - Delphox Gen. 7 - Silvally Gen. 8 - dunno, barely know any

You don't need to Rock Smash to get deeper in the cave below the Grand Staircase. Walk south towards a bunch of ledges - they lead to different paths depending on where you go down and only one of those paths leads deeper into the cave while the other ones loop back around.

Bronzong needs to survive a turn to set up, so probably something that draws attacks away. It shouldn't really have much trouble surviving since afaik Typhlosion and Darmanitan can at most hit it for neutral damage with Darmanitan's Hammer Arm; Incineroar can probably draw Darmanitan's attention away and get cleared out for the Ground Types to take over.

Catching a Bronzong on Route 3 and teaching it Trick Room shoud help. One of their potential Abilities is Heatproof which makes them immune against Fire. With Trick Room active the Ground Types should be able to deal with Charlotte's team. If your friend picked up the Protector from Iolia Valley they could use that to evolve Rhydon too.

The most important points of EV training are that 1) a Pokémon can only collect at most 510 EV total and 2) each stat can only have 252 EV at most. These two restrictions mean that you can max only two stats of a Pokémon with a handful of leftover points to spare. For general competitive Pokémon there's a ton of considerations to give your Pokémon the exact right EVs to be able to survive certain attacks or be faster than certain other Pokémon, but a lot of that doesn't really apply in Reborn due to Field Effects and whatnot. Your best bet would be to just identify the two most important stats of the Pokémon you want to train and then find some place were you can do that quickly using the various "Power" held Items. For fast attackers there's the aforementioned Woobats and for 'Mons that want HP there's Grimer fishing early on or wild Gulpin/A-Grimer in the WTC post-Agate. To my knowledge there's no other spot in the game where you can get encounters giving only one specific kind of EV as quickly as these two. Retraining EV for your old Pokémon should certainly boost their performance, but it can be rather costly to get rid of the unwanted EVs so you'll have to decide for yourself if it's neccessary/worth it. Breeding is usually mostly done to get perfect IV, but those have a lesser impact compared to EV; for the most part resetting encounters or catching several wild Pokémon until you get one with "decent" IV (for me personally 20+ in all the stats it needs) will do fine. Breeding perfect IV gets more involved the more perfect stats you want, although for just one or two stats it can be very quick if you already have the right breeding tools ready (i.e. compatible parents with perfect IV in one of those stats and the "Power" items to guarantee passing those on). Breeding for Egg Moves is another matter, but Move Tutors can let you skip that in a lot of cases.

@DerpierknightSince you have a Rhydon Trick Room should be a good idea. Primarina might work under it too, as long as you can somehow stop Charlotte from changing the Field to Burning. The caves on Route 3 also have Gravelers I think which can work just like Rhydon; if you picked up the Protector from Iolia Valley and have a Link Stone you could also evolve your Rhydon. If you need a turn to set up Wide Guard can help with that since Typhlosion tends to spam Eruption/Heat Wave and Darmanitan knows Rock Slide. side note: While Gardevoir is undoubtedly a great Pokémon both of its Types are already covered with other Pokémon in your team, so it or one of the other two might not shine as well as they usually would.

With how much trouble you seem to be having are you sure you're not playing in Intense? If you're lacking in offensive power Fearow could be a good option; its learns Aerial Ace and evolves very early giving it some decent power in the early game. For Lucario a Sturdy Geodude with Bulldoze might be helpful so you have to tank less of its attacks. I don't know how good Xatu is but I know it can make use of quite a bunch if Fields used in the early gyms.

You might know this by now but your theory on Karrina is spot on. The rework of the game's beginning made it really obvious too with her saying something to the tune of "Okay I think I stalled you long enou- I mean I think we're done here!" Someone needs to make comics out of every time you're trying to get the game to remember that you can do the thing while the characters ignore you. I always think that shit's hilarious.

I don't usually play defensive mons so take what I say with a grain of salt, but I'd say it depends on what you want out of it. Clefable is a defensive mon with a special focus so it plays a similar role to the Blissey you already have on your team. Blissey has unparalleled special bulk with the trade-off of being made out of paper on the physical side and having very little offensive capability. Besides stalling it can play a healer role with moves like Wish and Heal Bell, at least if those moves are currently obtainable on it. For actually defeating enemies I think it mostly relies on Toxic since it can't deal much damage itself. Clefable is a mixed bulky mon with a Special leaning. I think its biggest draw is that it has Magic Guard to protect itself from status and hazards which makes it harder to cut through its bulk. Compared to Blissey it has significantly less special bulk but in exchange can also take a hit on the physical side and can do some damage with STAB Moonblast. Because of these last two points I think it's better suited to general gameplay while Blissey is more of a specialist for cases like Dittoceus. Clefable would also be pretty well covered in your team since you have counters to Poison, Steel and Fire Types while Blissey is under constant threat by any physical attacks. As I said I don't usually play defensive mons but this is what I gathered from checking into their respecive playstyles for a bit. Their performance will obviously vary depending on which of their staple options are actually currently available in Reborn. TM Toxic for instance won't be available until quite a while later.

Seaking is just kind of really bad so replacing it would be the efficient thing to do. There's nothing wrong with keeping it if you're particularly attached but sooner or later you'll notice that it won't be able to keep up. If none of the current options really appeal to you could just wait until something else shows up. Here's a handy thread for checking which Pokémon of each Type become available with each Gym: Squirtle should definitely be available at this point. I remember the event was pretty inconsistent at some point but I've never done it myself so I don't know if it's been fixed by now.

It's a Magikarp but you don't actually get it until waaay later, around Lv. 80-85 iirc. You can get a Squirtle from Byxbision after the gym there; a cave in Chrysola forest has an Eevee that you could evolve to Vaporeon; If you allied with Team Aqua you should be able to get a Carvanha by now (it's notable for having Destiny Bond as a possible Egg move); Azurine Island has Shellos. If you can wait a bit longer North Aventurine Forest has Dewpider and 7th Street has Piplup.

Ah so it is. It used to be available earlier but I couldn't remember how exactly.

I very strongly recommend Flygon; it has a great natural movepool against many of the upcoming leaders and can make use of quite a number of TMs as well. You can get one once you get to Spinel Town by trading a Mothim for a Trapinch. Archeops is one Pokémon that works very similarly but I forgot if the fossil for it is still available at that point. Scolipede would be a strong upgrade to Kricketot available from Byxbysion that can also serve as a Batton Pass Support. Alternatively you could get a Yanma from Azurine Island. Also sidenote: you can actually already EV train pretty easily at this point. You only need I think two or three stickers for the "Power" items to become available at the Dept. Store and the lv.5 Woobats in the first accessible part of the railnet make great grinding targets for anything that wants Speed. Fishing for Grimers at Coral Ward is similarly effective for HP EVs. (If your game tends to lag in outdoor areas you can fish in the building that has Amaria's boat in it once that's open.)
