Try to teach Arcanine Flare Blitz and Extreme Speed, and Wild Charge as well. You can even put him a choice band from the magma gang sidequest to augment it's power. Overall, your team seems pretty solid. I think you should swap Donphan for Flygon, since the upcoming battle with Sapphira seems pretty difficult, and you can benefit of its access to Dragon Dance.

Mewtwo and Mew will likely be in the Glitch World, with some event related to T3RR4, or something, seems fitting for these two. I think Mewtwo will be in the place where you fought it (cerulean cave) and Mew MAYBE, just MAYBE will be below a truck

You can find rocks in the Citrine/Ametrine mountain

You can get clues to the Torchic egg event, there's the magic square puzzle (or at least something related to it) a house that rewards you with stuff like mega stones for pokedex completion. Agate city doesn't have that much to offer, but it still have some sidequests.

You can always use the weather change mod: https://www.rebornevo.com/forum/index.php?/forum/76-the-mod-market/

You don't actually have to burn the field to win, you have pretty good pokemon in your team. Scrafty is wonderful for Porygon Z, and then you can sweep with Blaziken, level up him a little, til' level 57, it learns Sky Uppercut, and bam, the fight is done. Which pokemon do you have most trouble with? Otherwise, you can try to make Porygon-Z get a attack boost, and then make Blaziken use bulk up a few times, as long as it survives, and then sweep easier, since some of the threats in his team are OHKO'ed by Sky Uppercut, like Cinccino, Swellow, Porygon and Bewear

Considering that, with the passwords feature, you will be able to do monotype runs, it won't be necessary. And there's still the starter mod, so i don't see why they would do that. Lore wise, starter pokemon are sparse, and they keep telling you that during the game, like the sidequest in the Grand Hall with the starter's eggs, for example

First of all, this version it's amazing, even though it has small changes, thanks a lot for the changes made. The slots mechanic it's neat, and the HP speed is much appreciated. I haven't tested for a long time, since it's been out for small time, but i do want to ask something. Does Earthquake have an animation now? Btw, that Aurora Veil animation is GORGEOUS, i always have an A-Ninetales in my team, and it's nice seeing that animation. Keep up the good work!

I put tailwind with Whimsicott, and Rain dance with a Jolteon, and then swept her with a Swift Swim Omastar, and an Araquanid

She's obviously dead. Plot wise, i would not have the same impact (her being alive) on the events of Devon. The idea is to show Lin's personality and power. The events leave a message of lost hope, that can be recovered, however, which is further expanded by Adrienn's speech.

Nice. Nice. Are you planing on implementing nature mints?

When Sigmund talks about "Lizzy" he's actually referring to his sister, Elizabeth Connal, not Lin. There's actually a grave of her in the Beryl Ward at the graveyard.
