The ending of this game was... interesting.
Literally the only challenging part of the Elite Four was Siebold's Gyarados. During my first battle against him, it managed to get off five Dragon Dances... Stupid Full Restores... I literally couldn't do anything against it because of those and the healing. That's what ya get for not having an Electric type or even any Electric moves on your team, though. Got him easily enough the second time through relying on the fact that he predictably Dragon Danced, allowing me to whittle him down with Gogoat until one Full Restore was wasted, then got lucky with Mega Blastoise's Dark Pulses doing enough damage for the second heal to not trigger.
Diantha was a pushover but oh my god finally somebody with six Pokémon on their team! (Except six Magikarp guy, of course.)
It was the battle after that that caught me off guard. I did not expect to fight AZ. And reuniting with his Floette was pretty touching. But most of all, I love how you were recognized as Champion and the person who beat Team Flare. No more of the silly NPCs saying post-game "I heard somebody beat Team ____, I wonder who it was..." That's right, it was me, and I get to be proud of that.

Everyone else who helped along the way:
And I'm not done yet with these! I've still got some post-game content to get through and that'll probably involved getting Friend Codes from everybody, so stay tuned for that.
