If you refer to the fight at Ametrine mountain then I think you seriously need to really find some type coverage since most of your team are easily counter by his pokemon. With your team now the best chance you have is set up and sweep with gradevoir. Try to set up when he sent Starmie out since calm mind boost your sp.atk and sp.def then sweep his team out of the mountain gl:) In case you mean double battle at fiore mansion. Just take care of Fern for Florina and she'll take care of most of blake team for you gl:) Ps. Pls do formatting next time. It's really hard to read also pls mention which fight since some character is fought more than 1 time.

Did you have a back up save option enable? If you do try loading it instead of normal save file using this guide. You might be able to find some back up save before the event you stuck on. PS. In case you can choose where you go back(Save file name will tell you like badge 3 mean somewhere after Shelly fight.) You might want to go back and stock up since at that point of story it'll be a long while before you can go back to Reborn.

You can find honedge in the mirage tower in tourmaline dessert same place where you can find Mimikyu. Just solve the puzzle it will be on the top floor.

Early game in this game is tough since there aren't a lot of good pokemon to use and hard to come by. Great pokemon in early game mostly come by static encounter so try explore everywhere you can. For now just deal with what you have and keep exploring and if you feel under level there is always a trainer in grand hall to grind. Also you can find a lot good pokemon via some static encounter or sidequest such as Espurr in Peridot ward, Growlithe in Beryl ward etc. Another tip I found out is unless you can sweep everything in your way, try find some tank or hazard setter or something that can disrupt opponent this will help a lot in a long run(AI in reborn is no joke like main game).

Your team and box are looking great to me. For Solaris his team hit pretty hard and fast with mega Garchomp as his ace, your team is not gonna outspeed him even with noivern in your box(I've already try that since noivern is my ace too ) From your box you may try using trick room since his mon are pretty speedy or train up Exacadrill since it can set up sword dance and sweep. From my playthrough I use this same strat but change Excadril Aegislash to set up sword dance while lower his team attack with king's shield then sweep them all with shadow sneak(240+ power with priority).

Pokemon Rejuvenation - Lycanroc dawn(midday is fine too), Decent speed with priority move and good movepool (stun lock and kill groudon for me lol) . Never take him off my team since start of the game. Pokemon Reborn - Aegislash, even though it's a bit late in the game but it wreck everything in following major battle including infamous 6v30 gaunlet.

I think Breloom fit your team more in my opinion since Breloom itself have more variey movepool compare to Roserade so you can change its moveset to fit your need on the fly also ability wise I also think Breloom is more useful to your team more because all 3 ability Breloom could have is pretty handy. Effect spore might save you in a clutch. Poison heal this open up to Facade+poison combo which is pretty devastate. And Techinician, if combo with mach punch and some stat raising move it's pretty scary.

This look fun I'll join in as well.

Randomus is not that hard to take down unless he can set up trick room. Just make sure that you can get rid of Reuniclus ASAP. Your team and reserve are looking good to take on him but you might want to bench Noivern and switch to Zoroark for this fight since the field effect give psychic type move gain a rock type so Noivern gonna get wrecked(Trust me on this Noivern is my ace too). You might want to try Persian from my playthrough oddly enough he wreck Randomus team pretty horribly(Techinician+Fake out+Assurance = RIP Reuniclus). About Leavanny, I don't think it's not a great idea due to how his field work. Don't get me wrong Leavanny is pretty good pokemon to train but just not for this fight.

Base on my experience, I don't have any leveling problem in early game since there a lot of Audino trainer around with variety of level range so lack of rare candy in early game or even the whole game is not that much of a problem IMO. Also the fact that EV in HP is not a concern since Ev reducing berry is not that late to be obtainable(Akuwa town is still consider early for me and it's very cheap).

It's pretty good already again don't worry too much about IV. About Florinia the only problem for her is her ace cardily since your level cap is 25 which mean you're not gonna have access to pokemon and move so you have rely on tactics rather brute force. Beside from my experience this game want you to use variety of pokemon rather than using one or two team of perfect or good pokemon, you always have to be able to change tactics on the fly. I'll share my team with you may be it'll help you see what you gonna have to face in your journey through Reborn. Have fun on your Journey and plz don't pull your hair out if you lose some major fight(just kidding ). REBORN TEAM AND RESERVE

IV recommend for Blaziken is attack and speed the rest is not that important Getting perfect IV is hard unless you gonna take time to find it or reset or ask around for perfect IV in the forum so the range I think that is consider good is 20 or above in desired stat. Still don't worry much about IV you can still beat this game without EV or IV training just adapt to around your pokemon you may face a brick wall sometime but you can do it. Good luck
