Location: Lorango, Second Round. In the Gym and in the Pokemon Centre (at the same time). The gym is blocked off with random trainers until the Pokemon Centre is visited.
Pokemon Centre (on entry): "Oh, h-hello [Player]-san. I'm waiting for the line at the Gym to get shorter. Apparently all the leaders are offering rematches to anyone that's already beaten them."
Gym (on entry): "Oh, hey there, [Player]! The Gym leaders are all offering Rematches! Are you here to have a rematch with Casey? Aw, who am I kidding, of course you are!
Hey, you've got that look in your eyes. Do you want to have a warmup match while we wait? I've got a funny-colored Snorlax now, too."
[Yes/No]
Yes: "Alright! I'm getting all excited! Ike Ike Go Go JUMP!"
TEAM:
Hans (AMBIPOM)
Lv. 73, Technician
Swift
Baton Pass
Nasty Plot
Taunt
Hans the Baton Passer. I have no personal experience in running an Ambipom, so the final "strategy" is going to be cut/pasted from Smogon.
Veloss (STARAPTOR) Lv. 72 @ Sharp Beak
Jolly
Intimidate
Substitute
Roost
Brave Bird
Close Combat
I really don't have much to say here. Substitute and Brave Bird, Roosting as needed. Close Combat is for covering Electric-, Rock- and Steel-types, who are usually the bane of a normal themed team. If we get Rotom, we switch to Chappi, and if we get Magnezone we switch to Snorley.
Tamako (BLISSEY)
Serene Grace Lv. 71
Seismic Toss
Ice Beam
Toxic
Softboiled
Ah, Tamako. The Special Tank of the team. Seismic Toss is for dealing with Steel, Water, Ice, Fire and Poison types, and Ice Beam is for all the others. Ice Beam gets preference when the attack is neutral to the enemy, especially if Hans Baton Passed some Nasty Plots to Tamako. Toxic and Softboiled are for Walling purposes.
Snorley (SNORLAX) Lv. 73 @ Leftovers
Immunity
Self Destruct
Earthquake
Body Slam
Crunch
Snorley the Differently-Colored Snorlax. Oh boy. He is somewhat less reliant on Chappi for dealing with ghosts than he was in older versions, but they still chase him away. Body Slam is the main move, Earthquake and Crunch are for type coverage, and Self-Destruct is for a last-ditch effort. Immunity was kept over Thick Fat, even though Smogon recommends Thick Fat over Immunity, as Poison and Toxic would force a Self-Destruct sooner I would like with a Last-Ditch Move. Granted, a burn would be more dangerous because of the added cut to physical attack strength, but there is no way to outright prevent a burn with Snorlax, and a Rawst Berry only works once.
Chappi (PORYGON-Z)
Adaptability Lv. 74, Holding Salac Berry
Substitute
Dark Pulse
Tri Attack
Discharge
Tri Attack and Discharge replace Signal Beam and Psybeam, and Dark Pulse replaces Recycle. Take that, Empoleon! There's a little bit of SubSalac strategy here to compensate for the now lack of the Recycle-Spammed Sitrus berry... or something. I don't really know.
Evelyn (ESPEON)
Synchronize Lv. 75
Psychic
Hidden Power Fire
Signal Beam
Trick
Meh. This is what I get for setting the level for this battle so close to the next battle's levels. See Encounter 4 for the strategy. No, there are no Choice Specs here, that's on purpose.
Payout Line: "Aww, no. I lost!"
[Win / No Battle] "Well, I guess you're ready for this gym, then."
(The gym is now deserted except for Himeko, PLAYER, Casey, and that advice guy. Casey and the Advice Guy are off-screen and are talking to each other, unaware of what's going on here)
"Why do I get the feeling I've forgotten something?"
(A second Himeko walks in with Daichi. Player and Himeko look at the doors)
Daichi: "...so we just need to tell Nonohara that [Player] saw you back at the Pokemon Center?"
Hime-copy: "Yes."
Himeko: "Oh, yeah, I forgot to end the copy spell." (Looks at player again. The ! appears over her head.)
"Oh.
OH CRAP! Daichi, get her out of here!"
Daichi: "..."
Hime-copy: "Umm..."
Himeko: "NOW! Sorry, [Player], I'll explain later. Meet me at the abandoned house in Estrella City, I'll explain there. If I remember, that is."
(The three of them exit. Advice Guy and Casey come out and assume their usual positions)
[LOSE]
Player appears outside the Pokemon Centre as usual, Himeko is standing nearby.
Himeko: "Well, you win some and lose some, I guess. I'm sure you'll be able to handle Casey, though. Why do I get the feeling I've forgotten something."
(A second Himeko walks out of the Pokemon Center and bumps into Player)
Hime-copy: "Oh! S-sorry! Umm, you haven't seen me around have you?"
Himeko: "Oh, I must have forgot to end the copy spell..."
(The ! appears over her head.)
"OH CRAP! Hime-copy! HIDE!"
Hime-copy: "... Yes, Himeko-san."
Himeko: "I'm sorry, [Player], but I can't explain now. Meet me at the abandoned house in Estrella City, I'll explain there. If I remember, that is." (Follows after Hime-copy. Daichi walks up from a random direction.)
Daichi: "I told her not to do that today, but did she listen to me? Nope. If she gets our memories erased for this... (He follows after them.)
