Farnsworth

Grass in the early morning. It is a rare encounter.

You find him in Apophyll cave, you access in the North part of the beach.

It is Stunfisk.

So it seems that Gardevoir was a serious leader in the online League. The entire premise of my theory was that because Gardevoir gained the fairy typing in Gen VI, which was something that happened after her time at the League, she could be a fairy trainer in-game (as opposed to being a psychic type trainer like in the League). But it seems that the reserve fairy leader was some guy that died during the PULSE attacks in Jasper. So yeah, he is definitely just a plot device and nothing else. But still, considering we got to battle (or will eventually battle) every Leader from the online League there has to be a point in the game where we face off against Gardevoir. And I just can't figure out a situation where this would happen. So having her as the reserve fairy leader would help with that issue. But now I'm starting to think that maybe GG will be the one to give us the Mega Ring and teach us about Mega Evolution. That would make some sense and would give us an excuse to battle her. Ame did mention that she was considering making Nostra Anna's ace. So I'm guessing that this is the reason Gothitelle is gone.

Before making my ranking I want to say that I love every single mainline Pokemon game. And while I do list some negative points and criticize some things it does not mean I don't love these games. 1. Gen II - Still my favorite to this day, has the best dex imo and also the Kanto postgame is amazing. 2. Gen VII - Has a good story and I liked how it shook up the formula with things like Alola Forms and Trials. But mostly I love all of the QoL changes such as streamlining the PC. The extra features are also a lot of fun. This gen has my favorite region, I really loved Alola. 3. Gen I - Mostly Nostalgia, it was my first generation after all and I still have some very fond memories of it. Also has the second strongest dex imo. 4. Gen V - I find this gen to be a tad overrated, especially the story. The story is ok at best, although I can see why people call it amazing because compared to the rest of the pokemon games (bar SuMo) the story truly is a masterpiece, but for a JRPG (or even when compared to fan games like Reborn) it isn't anything special. The dex is kind of a mixed bag, having both amazing designs and some very forgetful mons. Overall I do love this gen quite a lot, but I think it is pretty overrated. Still it has a lot of great points, like amazing post-game (BW2), a great region and some cool features. 5. Gen III - I like the dex and the fact that it introduced two evil teams. Secret bases are also a lot of fun and I loved the Battle Frontier. This gen has by far the best post-game. Other than that the region itself is somewhat annoying due to the abundance of water routes. 6. Gen VI - I love Mega Evolutions, the jump to 3d, hordes, the PSS and much more. However the story is bare bones compared to Gens V and VII, and also the region is pretty forgettable. Doesn't help that it essentially has next to zero post-game content. 7. Gen IV - Quite honestly I don't remember much about this generation, which is why it is ranked lowest on my list. The dex is amazing, but it has way too many evolutions and pre-evos (I'd rather have them spread across more generations). Although I do remember that the pokemon distribution in these games (Diamond and Pearl) was a mess and that some types (like Fire) had next to no pokemon available until post-game. I never played Platinum though, so this point might have been something they fixed. EDIT: My rank consists of only the mainline games, since I don't really count the remakes. But if I were to include the remakes in the ranking it would be:

Your team is very solid, so much so that I suggest keeping the members as they are. Though I'd recommend changing their movesets and items a bit: Give Escavalier either Drill Run or Knock Off. Also change its item to the bug or steel boosting item. For the Swampert remove Surf and give it Rock Slide. Calm Mind is much better on Gardy. You could instead try some coverage moves like Shadow Ball or Grass Knot. Also consider running Trick Room to help out Escavalier and Swampert. Take out Light Screen and Discharge from Electivire. Give it the two remaining elemental punches (Fire Punch and Ice Punch). Change its item to Expert Belt. Brick Break is useless on Hera. Give it something else like Bullet Seed, Shadow Claw, Aerial Ace or Dig (I think we have access to it by now). Change its item to Flame Orb to abuse Guts.

Hmmm I guess that shoots down the theory of Gardevoir being the reserve fairy leader. But who could possibly be this fairy leader? We will ever find out who this mysterious person is? Do you know more or less the point of the story when Ame explains this? I'd like to take a look at the dialogue and I don't really know how to mess with RPG Maker. At this point it does seem this reserve leader is just a cop-out for the plot hole involving Adrienn. But there might be more than meets the eye to this story.

EXCUSE ME!? This actually works... We must abuse this before it gets patched in episode 17!

Every single pokemon will be available in-game, this is something Ame has confirmed multiple times so UBs won't be any different. Considering the recency of Gen VII I don't think UBs will have any relevance to the main story but they will most likely get post-game events. That being said, if the Cosmog event doesn't involve Nebby getting into bags I will be very disappointed.

Expanding on Anna it has been heavily hinted that she is one of the E4. Not to mention that her ace is (most likely) Nostra, and Jirachi is a Psychic/Steel type pokemon meaning she couldn't possibly be the reserve fairy leader.

I just double checked that same cutscene in E15, and there is no mention whatsoever of the reserve Fairy Leader. At the very least that piece of dialogue is brand new to E16.

So I've been recently doing a Ground type mono run and during my playthrough I came across a very interesting piece of dialogue coming from Radomus: I didn't remember seeing this dialogue before on my previous playthrough, so I searched on youtube to see if I could find it there. And it seems like this has been added in episode 16, which has some interesting implications. This dialogue is important because this is the first time there is any mention of a reserve Fairy Leader in the league. The question is who could this leader be? Ame has confirmed that as of episode 14 we have met all of the characters, so this mystery leader has to be someone we know. I did some research on the online Reborn League, and Adrienn was the only fairy type leader in the history of the league. Not to mention that every other leader already seems to have a role in the game and the in-game league, whether it be being E4 (ex Heather, Laura), a gym leader (ex Shelly, Luna, Charlotte), a challenger (ex Cain, Fern, Victoria) or just not having any connections to the league (ex Arclight, Sigmund, Lin). All except for one that is. Apparently Gossip Gardevoir was a leader in the online Reborn League, she even had her own trainer card. However, I'm still not sure if she was a serious Leader or a troll one (kind of like Sandy) since she listed Radomus as her ace in her trainer card. Another problem is that she was a Psychic Leader and not a Fairy one. That being said, in Gen VI Gardevoir gained an additional typing, and that typing was Fairy. So that could be used as a justification to make her into a Fairy type trainer in-game. Moreover, Gardevoir was quite aware about Adrienn being the fairy leader: She was aware of Adrienn without even meeting xem. The only reasonable explanation to that is that she is in fact the reserve Fairy Leader and because of that Ame explained Adrienn's situation to Gardevoir. So, if Gardevoir is actually the reserve Fairy Leader there could be some interesting implications for the story, especially since this was (maybe) added in E16. I don't really know what could come out from this (if anything). But it is an interesting discussion if anything. Though it could also just be a cop-out from the whole Adrienn being gone for 10+ years plot hole and I'm just reading too much into things. So, TL;DR There's a reserve fairy leader, and that might be Gossip Gardevoir.

Losing the gemstones most certainly will lead to a catastrophe. But I guess the king could instead be the 'Meteor'. Radomus is a cryptic person, that is just who he is. The whole Citae D'Arc story bit is more than enough proof of that. Why didn't he say anything about Gardevoir being able to teleport? Why didn't he say anything about El's ditto? Why didn't he tell us what he would do with the pendant? That is just who he is, he doesn't like giving out information or maybe he is just testing the MC. As of now he is just a very cryptic person. El has grudges with quite a lot of people, just because he holds one with Radomus doesn't mean he isn't passive. If anything El is a very aggressive person that does whatever it takes to get what he wants. Radomus seems to be a very careful person, always assessing the situation before making his move, which is why I described him as passive since he is more of a observant type that doesn't do things without good reason. They probably crossed each other before most likely because of Luna, since when Bennett says she is in the Vanhannen Castle El replies with a "Of course". And I really don't see how Radomus could be part of Meteor and El (a very loyal follower of Team Meteor) have a huge grudge against him.

Hmm if true then I'd say E18, since 17 has a lot of mapping with the desert and stuff. Though I could see Amy's gym being right after Tania.

My predictions:

I'm guessing that the 'king' would be the four gemstones considering their extreme importance to the story and the fact that they can open the doors to the 'Meteor'. Him having Team Meteor's uniform doesn't mean he was ever a part of it, he could have grabbed it from a grunt or something. I doubt that he would be part of Meteor, why would he directly confront El if he was indeed part of the team. He seems to be more of a neutral party, that only fights back when provoked.

Okay, so your post reminded me of a certain thing Ame did here on the forums a while ago. And after a lot of digging to try to find this suited lady. I must say I am at a complete loss, though I might as well share my findings. Warning the stuff in the spoiler tag contains massive spoilers for story post episode 16:

My suggestion: Drop the nuzlocke and keep it as a mono grass run. It is literally impossible to do a Nuzlocke in Pokemon Reborn, since there are portions of the story that requires you to lose battles. Even a normal mono run is very hard, but a nuzlocke (especially a mono nuzlocke) is impossible. Trust me on this. Anyway, I enjoyed the video quite a lot. Keep up the great work! Just as I said, consider dropping the nuzlocke part since it would be pretty sad to see your run ending early.

You can find Solarbeam in the secret room in Beryl Library. You need to interact with the colored books in a certain order. You can find this order in a locked room in the Sanctum, the room where you found the 'dark material' (it is in the order the colored statues are in).

I am currently doing my first mono run, for the ground type, and I have to say it has been a blast. Although not as challenging as I initially thought, it is still much harder than a normal run (especially Fern's god forsaken Ludicolo, I'm glad he got rid of that disgusting thing). And I have been falling in love with pokemon I haven't ever used before like Krookodile. If you want to do a mono run, try going with a type that you don't normally like that much. I first planned on using my favorite type, Water, but then I gave up on that idea since I thought it would be too easy. And I have to say that I am glad I did it, it made me appreciate pokemon I would have never used normally. The run becomes much more interesting when you are forced to use pokemon you normally would avoid in vanilla runs. So I definitely recommend going for the types with less pokemons or with pokemon you usually avoid.

Destiny bond is always a great idea to take out these strong mons. So maybe having a very tanky Weezing that can take 1 hit from Arceus with Destiny Bond would be a good strategy.
