Did they put Seeds on their pokemon to hold? iirc Seeds can set the Trick Room effect on Dimensional fields, so you might not have noticed that Trick Room was active if the dialogue was quickly clicked through and I guess it's unlikely that the Ribombee was holding a Lagging Tail, or using a low priority move (doubt it even learns one)

You can challenge specific trainers with Debug, even the different difficulty versions. Unfortunately the field won't be the one from the original fights, but from the area you are in, so you have to travel to a place with the original field if you want the "real" fight. That's probably the closest to what you are looking for.

save slot 2 means it's Game_2.rxdata, Game.rxdata would be slot 1 also you don't have to do anything to your save files when you reinstall the game, since they are in seperate folders nothing will happen to the save files you don't even need to delete your old game folder, just extract the game in a differently named folder and try starting the game from there before you do anything to your old files I'm not that knowledgeable on what the error messages mean, but it might be that your save file got corrupted. Try removing Game.rxdata from your save file folder and then start the game and try to switch the save slot

1) Psychic, Normal and Fairy types are really good on her field. Go to Amethyst Cave. There are several helpful pokemon you can catch there, like Natu or Solrock/Lunatone, and especially in the Amethyst Grotto, the place where you fought against Spirit Keta, like Jigglypuff and Girafarig. There is also Cutiefly in that yellow meadows part in Amethyst Cave, the part that is blocked by Rock Smash boulders and Cut trees. 2) Get the TM Psych Up. Marianette likes to set up Cosmic Power, so copying her stats in one go can be really helpful. The TM can be found during the Hidden Library Quest 2 (Sheridan Help Center). Or catch Lunatone/Solrock in Amethyst Cave, since they both also learn Cosmic Power.

no there is no easier way, if you have the shiny charm then you already have the highest possible chance. You just have to be patient and keep trying

it changes form depending on where you send it into battle. For Trash Cloak you need to fight inside a building

I like Sceptile in combination of its Unburden ability with the Field Seeds you can find lying around as hidden items, Both Speed and other stats get boosted. And all Grass starters in general can learn Nature Power. You get the TM as reward for beating the 2nd gym, and it can make use of the Reborn fields to become many different moves which are additionally boosted by the field, giving you a variety of good coverage moves (except for gym fights, where it usually becomes the same type as the leader's type, unless you are fighting the Ice leader who gets destroyed by Nature Power)

if you mean the lag of a few seconds every time before a move is used, then that's "normal" in the current version, it's gonna be fixed for the next update. The link below has a download for a modified version of the current episode, which is pretty much without any lag and runs much smoother.

change the weather - that will deactivate her field for as long as the weather change is active (try using one of the Rock items which prolong weather as well) I think TMs for weather can be bought in the pokecenters in the Cellia districts

if you want all the info on the fight: (this is for Intense, but still very useful for any difficulty) https://pokepast.es/40d41064f670dc41 There are lots of ways to beat this. Very easy ways would be Destiny Bond, Perish Song, Endeavor, Curse or Toxic. But other things can be very helpful too, like - Leech Seed on the Gardevoir to heal tons of HP. - The Sweet Veil ability so your team cannot fall asleep (Ribombee for example, which I believe can be caught in town or nearby). - Imposter Ditto (can also be caught in Hiyoshi City, but very rare). - Terrain moves to prevent sleep or get a general advantage, or a Seed for Trick Room as already mentioned. - Teach your mons Sleep Talk to make use of the sleep, for physical mons you could even teach Facade for double damage. - Magic Bounce/Magic Coat to reflect the status moves back.

RMs are TMs from older generations, and I think those weren't updated in Rejuv to reflect the gen 7 learnable moves, which is why Alolan Sandslash, a gen7 mon, doesn't learn Hone Claws through RM, since it was a TM in gen 5 iirc. (So any pokemon introduced in a later gen than when the TM existed can't learn that RM). If you want to see which mons can learn a specific RM, you need to look up in which gen that RM was a TM (bulbapedia, serebii, etc.), and a list of the pokemon that learn it in said gen.

you could teach Rain Dance to weaken her Fire moves, and stop her from burning the field another option, since you have Avalugg, is to relearn Wide guard at the circus, which helps with blocking her Eruption and Heat Wave attacks

you can breed eggs of the mons you need and hatch them in 7th street, then they should be acceptable for the quest

Look in your game folder, Graphics / Battlers, there you can view all shinies and look for one that you like

You can load a backup save from before you entered the house to get out without losing progress. Search your PC for the file 'Game.rxdata'. The folder it's in also contains recent backup save files. You just have to rename the Game.rxdata file to something else, then rename the most recent backup file to 'Game.rxdata' instead, then load the game. Also I'd recommend not to keep weak moves like Cut or Rock Smash on your team, especially for major fights like these. And keep in mind your pokemons' attack stats: Not every move is useful. Rhyperior will barely do any damage at all with Surf, because it's a special move, but Rhyperior's special attack sucks.
