I finally got around to getting all of the trophies.

-----------------------------
Super Triples Streak: 374 wins
For Triples, I decided to try out a rain team that was heavily based on the rain teams that R Inanimate used in the Battle Subway, by which I mean most of my team uses identical Pokemon! I was just curious as to how viable rain was despite the nerfs.
Politoed @ Choice Scarf
Timid
ivs: 31/x/31/31/31/31
evs: 4/0/0/252/0/252
stats: 166/75/95/142/120/134
Drizzle
Surf
Ice Beam
Psychic
Focus Blast
Only here for Drizzle. Rain didn't gain any new weather setters like sun did, so I have no choice. It's still alright though. It's in an awesome speed tier for Choice Scarf, outspeeding Jolteon and co. by a single point.
It'll use Surf most of the time to deal great damage and activate Absorb Bulb. Ice Beam is for Dragons. Psychic is mostly for Toxicroak. Focus Blast is filler that is mainly useful for Cloud Nine Lickilicky, and possibly Empoleon and Lapras in clutch situations.
Ludicolo @ Absorb Bulb
Modest
ivs: 31/x/31/31/31/31
evs: 4/0/4/252/4/244
stats: 156/72/91/156/121/121
Swift Swim
Surf
Grass Knot
Ice Beam
Fake Out
Extremely powerful after Absorb Bulb activates, and decent even before then. Unfortunately it's faster than either of my other leads so its first attack will generally be at 0+, but that's a minor problem since rain-boosted Surfs are so strong anyway. Grass Knot deals with Water-types, Ice Beam for Grass- and Dragon-types, and Fake Out to deal with particular threats (e.g. opposing Fake Outs, Trick Room, etc.).
Ludicolo is in the middle for 2 main reasons. Firstly, it is my strongest attacker, so having it in the middle allows me to maximise damage against all of my opponent's Pokemon. Secondly, it allows me to Fake Out any lead regardless of what position they are in.
Speed EVs allow it to outspeed as many opponents as possible in the rain (Scarf Terrakion and everything below).
Heliolisk @ Focus Sash
Timid
ivs: 31/x/31/31/31/31
evs: 4/0/0/252/0/252
stats: 138/66/72/161/114/177
Dry Skin
Thunder
Surf
Protect
Rain Dance
Given that Rain teams can struggle against opposing Water-heavy teams, having an Electric-type as a lead made sense. Heliolisk is the obvious choice thanks to Dry Skin, which allows me to Surf as much as I want without consequence. I just wish it had a few more points in Speed...
Heliolisk mostly uses Thunder, to finish stuff off and throw out paralysis. Surf hits reasonably hard in rain despite the lack of STAB, and it also acts as a back-up activator of Absorb Bulb should Politoed be preoccupied with using one of its other moves. I originally had Grass Knot over Protect when I started but I found myself rarely using it. Heliolisk has awful physical bulk and is a tempting target for physical attackers; Protect stops these guys in their tracks. Rain Dance is solely to deal with opposing weather starters efficiently. It's faster and safer than trying to switch Politoed out and in again, and in any case there isn't really anything else in Heliolisk's movepool...
Gastrodon @ Rindo Berry
Quiet
ivs: 31/x/31/31/31/0
evs: 148/0/108/252/0/0
stats: 205/89/102/158/102/39
Storm Drain
Surf
Earth Power
Ice Beam
Protect
A "glue" for this team that helps deal with Trick Room and Electric/Water-heavy teams. Storm Drain is fantastic and makes Gastrodon very powerful very quickly. Sometimes its low Speed works against it, especially if it has to take multiple hits when switching in, but it can still be useful with Protect to absorb obvious incoming-attacks from opponents trying to finish it off.
Scizor @ Scizorite
Adamant
ivs: 31/31/31/x/31/31
evs: 252/252/0/0/0/4
stats: 177/200/120/57/100/86 --> 177/222/160/66/120/96
Technician
Bullet Punch
Bug Bite
Superpower
Protect
Scizor is a great switch-in for Grass-types, gives me some physical coverage, and is just a great Pokemon in general. Not much to say here, other than the fact that Scizorite allows me to use Life Orb on my last Pokemon without the dreaded item clause getting in the way!
Kingdra @ Life Orb
Mild
ivs: 31/31/31/31/31/31
evs: 0/60/0/252/0/196
stats: 150/123/103/161/115/130
Swift Swim
Surf
Waterfall
Dragon Pulse
Protect
Kingdra is like a back-up Ludicolo. It allows me to play non-conservatively with Ludicolo, and should something go wrong then Kingdra can come in and take its place.
It uses Surf most of the time, with Waterfall being used depending on the Pokemon I'm attacking. I have to be careful when Gastrodon is out though, since Storm Drain will prevent Waterfall from hitting its intended target. Dragon Pulse is an alternative STAB which can also hit across the battlefield, similar to Talonflame's Brave Bird.
Speed EVs outspeed Scarf Manectric in the rain. The only things faster are certain opposing Swift Swim Pokemon. I maximise Special Attack and shove the rest in Attack to buff Waterfall.
Overall, I'd would say that rain is still perfectly viable as long as you are aware of certain threats and how to deal with them. Originally, I thought that the nerf to rain's lasting time would be a problem, but it was barely an issue at all. Most battle finish before the rain stops; only around 5-10% of my battles resulted in the rain effect ending, and by then I was usually too far ahead anyway.
No, the real issue with rain now is all the new trainer specialties that seem to have been designed to "counter" rain somewhat. You have the usual threats like Legendary teams, Rain, Hail, and Water-heavy teams, but now you also have Chefs and Rangers that use lots of Water and Grass types (along with the usual Starter trainers that are basically the same as Chefs). Roller Skaters specialise in Electrics, and Scientists are also tough since they have Electrics PLUS Poison-types (with Muk and Dry Skin Toxicroak being among the more threatening ones) PLUS Wide Guard Bastiondon and Snow Warning Aurorus. And then there's Ace Trainer Bunny, the "high Special Defense" trainer, who can be tough to break depending on what she uses (particularly Goodra).
Looking at Pokemon more specifically, there's all the new hidden abilities to consider. Many of these aren't too bad but you still have to be ready for stuff like Dry Skin Jynx, Storm Drain Cradily, and Swift Swim Poliwrath. Assualt Vest is an interesting threat, although Magnezone is really the only one I cared about. Cloud Nine is also annoying, with Lickilicky being the worst one here. It's hard to kill quickly and Lax Incense + STAB Explosion is scary. Altaria also has Cloud Nine but is easier to deal with thanks to the Ice weakness. All of this is on top of what was already threatening to rain in the Subway.
Regarding weather starters, Politoed, Ninetales, and Aurorus join Abomasnow, Tyranitar and Hippowdon as potential threats. Thankfully, Ninetales and Aurorus aren't too difficult to deal with being Water weak and all, and Politoed starts the weather that I abuse anyway. Abomasnow is still the most dangerous weather starter.
Despite all this, it is still possible to get long streaks with a rain team. My team has options that allow it to deal with most of these situations. Also, the addition of hidden abilities can work in my favour (e.g. against the aforementioned weather starters) and the fact that most trainers use set 4 Pokemon now makes previous threats rarer/non-existant.
Losing Battle: LDHW-WWWW-WWW7-KCPU
I haven't actually watched that battle since I recorded it but I wasn't really concentrating and I remember making a bold play by trying to use Earth Power on Zapdos hoping it would Roost, but it used Heat Wave instead. At the end it was Zapdos vs. Heliolisk, but with Heliolisk's speed already being lowered and it staring to run out of PP there was little chance of victory (would need a paralysis at least but it didn't happen).
-------------------------------
Super Multi Streak (with AI): 57 wins
I've been putting off doing Multi for a while. I had a look at my options a while ago and wasn't excited by what I saw. After finishing my Triples streak, I had another look and upon closer inspection of the actual sets of the Pokemon found some with potential. I went with the following:
AI team:
Porygon2 @ Choice Specs
Modest
ivs: 31/31/31/31/31/31
evs: 252/0/0/252/0/0
stats: 192/90/110/172/115/80
Trace
Tri Attack
Thunderbolt
Psychic
Ice Beam
Specs Porygon2 has great power, bulk, and coverage. That's all there is to it. It actually managed to survive most of my battles, mostly because of Mat Block and the opponent's preference for attacking the frailer Greninja that was its partner.
Trace is pretty handy too, although Analytic would probably be better most of the time.
Blaziken @ Choice Band
Hardy
ivs: 31/31/31/31/31/31
evs: 0/252/0/0/0/252
stats: 155/172/90/130/90/132
Blaze
Flare Blitz
Shadow Claw
Thunder Punch
Earthquake
I would prefer something different here but Blaziken is ok even with Blaze over Speed Boost. Band Flare Blitz is powerful and Blaziken is fast enough to get by. However, I don't like having a Choiced Pokemon as a back-up in the hands of the AI. Sometimes you simply can't tell for sure what Blaziken will use against opponents that are on the brink of fainting, which is fairly common when Blaziken comes out. This actually cost be a streak at 46 wins. I was against a near dead Gallade and a Mismagius, with a yet-to-be-revealed Pokemon to come after Mismagius, and I only had Scizor and Blaziken. I Bullet Punch Gallade expecting Blaziken to Flare Blitz Mismagius and... it uses Earthquake. So I was left to beat a 252HP/252Def Mismagius with Protect while my partner continues to hit me with Earthquake. I managed to beat it on the same turn I died, but the last Pokemon was Medicham which barely survives Earthquake and kills Blaziken with Psycho Cut.
Because of this, I'd rather have Blaziken come out AFTER I know all the Pokemon I'm facing...
My team:
Greninja @ Focus Sash
Timid
ivs: 31/x/31/31/31/31
evs: 4/0/0/252/0/252
stats: 148/93/87/155/91/191
Protean
Ice Beam
Grass Knot
Scald
Mat Block
Mat Block is great for protecting Porygon2 against Fighting attacks, and Greninja tends to draw attacks away from Porygon2 simply by being easier to kill. Other than that, it's fast and powerful with great coverage.
Scizor @ Scizorite
Adamant
ivs: 31/31/31/x/31/31
evs: 252/252/0/0/0/4
stats: 177/200/120/57/100/86 --> 177/222/160/66/120/96
Technician
Bullet Punch
Bug Bite
Superpower
Protect
Kinda just threw this here. Don't have much to say other than that it's a great Pokemon.
Losing battle: EAGW-WWWW-WWW7-KCPH
Overall this set up is a bit soft against Electric-types, especially those that are faster than Greninja that I can't stop with Mat Block. I ultimately lost to a Jolteon+Cobalion lead combo, with Flareon and Suicune as back-ups. There wasn't much I could do.
-------------------------
There are some things I've been thinking of trying in the other modes but I'll probably wait until the 3rd gen remakes come out and see what's in those before I try any more battle facilities again. I actually have a feeling that the Emerald Frontier WON'T be back but who knows?
