Yeah you're right that Swanna learns Brave Bird at 47, but since yours is a female it wouldn't help you much because you wouldn't be able to breed it onto a Zubat, and since Brave Bird isn't an egg move for Ducklett it couldn't pass it down to a male offspring.

The problem with that is that Pidgey can't pass Brave Bird on to Crobat through breeding. I think the earliest way to get it is to use Headbutt to catch a male Taillow once you reach Chrysolia Forest, get it to level 41 without evolving so it learns Brave Bird, and breed it with a female Zubat/Golbat to pass it over. (Talonflame is technically available earlier, but it doesn't learn Brave Bird until 64 so not much help) Also I'm pretty sure it doesn't matter when you save the Day Care Couple to get the Ditto, just need to turn it into Makuhita in Blacksteam Factory, but I don't think it would help anyway since Brave Bird isn't an egg move for Ducklett.

If you hover your mouse over the boxes it'll show the name of each item, even if the icon isn't loading properly (I can list them off for you if that doesn't show either). As for the exact rarities, since the table looks pretty similar to the ones for Emerald-Gen 6, I would assume that the rarities for each section are the same; that is to say the Common is 30%, each Uncommon is 10%, each Rare is 4%, and each Very Rare is 1%. I haven't played Rejuvenation so I couldn't tell you if it's the same personally, but other people probably could.

You can buy your first Link Stone on the Grand Stairway after your 4th gym battle I believe, and you can find some on the ground pretty soon after (one in Beryl Cave I think but its a hidden item)

Really the hatching an egg on 7th Street doesn't work? I've seen that be the solution for a bunch of people so idk why the Vanillite would work differently.

Incredible, it's the moment we've all been waiting for!

I believe you can get them from mining yeah. There might also be a place you can get it otherwise, but I can't remember where it would be.

Nope, as far as I know it's just the standard mining loot table, so just RNG. If you keep soft-resetting you should eventually get one.

Unfortunately you can't get one until really far into the game, after your 13th badge. If you don't want to wait that long then you could ask somebody to trade you one. Otherwise, be sure to thoroughly explore the room of the Underground Railnet that exits right into the Chrysolia Region and then go to the Critical Capture shop in the Obsidia Ward.

It's right after you beat Blake at the peak pretty much.

The choices for that info should be not fighting Doctor Connal at the Yureyu Building and then staying downstairs at the Belrose House. You get some info pretty soon after that and then even more quite a bit later, at Ametrine City.

It is actually Terra that they're talking about, so it's hard to know what caused her to change so much. Also depending on which routes you've taken, it's possible to find out who the other girl they were talking about was, but that just adds even more confusion...

Once you reach 7th Street you get the ability to buy Ill-Fated Dolls, so you can still get the Elgyem, Baltoy, and Golett. Also for future reference, rather than selling items you don't want to keep on you, you can go to your own PC and select Item Storage. Then you can choose to Deposit or Withdraw any items you want (except Key Items and TMs I think).

I believe the event is supposed to be in Obsidia Park when the weather is sunny if that helps at all.

Turtwig you can get from one of the games at Agate Circus, Froakie you get as the reward for 300 Pokemon in your dex in Agate City, and you can find Tepig if you mess around with the Strength boulders in Pyrous Mountain for long enough.

I'm not actually sure what happens if you start it but don't finish it before a certain point, but generally it doesn't make much of a difference. It's also not a very long sequence, but I guess if you don't know where to look it could be tedious to run around the whole city a bunch.

You can actually do it shortly after you beat Corey, which is what's shown here. If you wait until later then the event is a bit different. But yeah, it's not a bug, and it is fairly known. Just look around the city a bit and you'll find out what's going on.

You don't really have to EV train, but it definitely makes the battles more manageable. You also get access to Power Items a few badges in so that makes it much easier to do.

You definitely don't need to wait until later, you're actually able to do it as soon as you beat Aya. You should be able to get to the level above through a different part of the wasteland and push the boulder down a hole to break a rock and get through. If you still can't find it then I might recommend looking up a walkthrough for it, or if it just actually isn't there then there could be something wrong with your save and somebody could help you with that too.

If it's your first time on Route 1 then you'll be coming up on a really tough battle soon, so I'd recommend a bit of grinding if you're far below the level cap (though your Blaziken might be able to carry you through the fight itself).

Yeah that's exactly what I had to do to get a Claw Fossil. Can confirm, it works.

You can catch Fletchinder and Talonflame in the Beryl Cemetery during morning and day time (and Talonflame extremely rarely on Teknite Ridge during morning and night). Also, if you only got one of the vending machine Vanillites, there's another in the Spinel Town Museum (or the Obsidia candy shop if you got that one) and you can catch Vanillish in Ametrine City.

I know Reborn has a shiny rate of about 1% (3% with Shiny Charm), and similar games like Rejuvenation probably have similar rates, so one of those would be relatively easy to do. For official games, you'd probably have the best luck with something gen 7 or later (SuMo, USUM, LGPE, SwSh) since those games have a higher shiny rate than most previous ones and all have a somewhat simple way to chain for them.

You get the Plume and Cover Fossils from games at Agate Circus. I'm not sure if you used to get them from this quest but I'm pretty sure the circus is the only way to get them now.

Empoleon's primarily a special attacker, so for your main Water move you'll probably have either Hydro Pump, Scald, or Surf (HP for the most damage, but unreliable; Scald for the nice burn chance; Surf for the utility in the overworld, decent damage, and hitting everything in doubles). You can also run Aqua Jet in addition to one of those special moves since priority is always nice and it can make use of your ability. Eventually you're gonna want to teach Flash Cannon since its one of the only special Steel moves out there, but unfortunately you don't get the TM until your 17th gym battle, so you might be waiting a while. In the meantime, I usually leave it with Metal Claw since its the only Steel move you get and its better than nothing, especially since its physical and works with Defiant too. I'd generally say this last slot would be for Ice Beam, but since the TM for it isn't available yet, I usually use the tutor in Agate Circus to teach it Icy Wind since it's a pretty good move even with the lack of power. You could also use the last moveslot for another special move like Grass Knot or another of the above Water moves, or you could go with an extra physical move like Brick Break or Shadow Claw. (The above reply also makes a good point about the Swamp Field activating Defiant, and I've even found, probably a bug, that the field actually activates Defiant twice per turn for some reason, so if you come across a Grass starter you'd like to use maybe keep that in mind)
