I am also having a hell of a time with Charlotte. I've already trained up a swampert from 5-67, but just can't get it to stay out long enough even if I bring down the weather. It has poor speed/def/spdef evs and ivs and just gets wrecked quickly by everything on her team.
Was hoping to run a trick room setup with prankster but unfortunately I beat Radomus before he gave out that TM, so I don't have it. Is there any way to get it if you didn't obtain it after that battle?
I've also had to heal in Calcenon so unfortunately teleporting back to Reborn city isn't possible anymore. I did that once while in the circus to pick up an ability capsule for Blaziken. Current team:
Swampert, Damp, 67
Brick Break
Rain Dance
Surf
Earthquake
Mamoswine, Oblivious, 63
Blizzard
Earthquake
Ice Shard
Thrash
Blaziken, Speed Boost, 69

Hi Jump Kick
Brave Bird
Luxray, Guts, 66

Discharge
Swagger
Crunch
Gengar, Levitate, 66
Shadow Ball
Dark Pulse
Curse
Confuse Ray
Alakazam, Inner Focus, 68
Psychic
Shadow Ball
Grass Knot
Recover
Remotely viable pokemon in PC:
Toxicroak, Dry Skin, 60

Magmar, Flame Body, 63
Flamethrower
Fire Punch
Feint Attack
Confuse Ray
Yanmega, Speed Boost, 65
Air Slash
Bug Buzz
Detect
Uproar
I do have heart scales so unlearned moves could be possible, but no ability capsules. A couple low-level pokes in the PC have prankster but I'm not sure if any of them can rain dance (and as said above, trick room out of the question). Generally what happens is I just get outsped and annihilated even if I can get up a rain dance or blizzard early - things just hit too hard and when the second ninetales comes out I'm toast since the rain dance / blizzard setters tend to be dead at that point. Oddly the most success I've had is what got me past the last few leaders: setting up on Blaziken and just Hi Jump Kicking the crap out of their team. But no one else can survive long enough and this strat keeps either of my surf/earthquake users from doing their thing. I'd prefer not to grind up an entirely new pokemon if possible - getting the swampert up this high already sapped a lot of my motivation to continue playing. Any ideas?
tl;dr field effects OP, c'mon Ame difficult is fun but Charlotte is absurd without counterteaming. And inb4 "I beat it on the first try because my team was fast and had five earthquake / rock slide users".
