I guess I'll bump this thread back to first page with an ok but not so amazing record. Exactly 100 streak in Double Battle Subway with this team:
Ambipom / Technician / Jolly @ Focus Sash
IVs: physical flawless
EVs: 4 Sp Def 252 Attack 252 Speed
- Fake Out / Return / Ankle Sweep / U-Turn
Latios / Levitate / Timid @ Life Orb
IVs: 31 / ? / 31 / 30 / 30 / 31
EVs: 4 HP 4 Def 244 SpA 252 Speed
- Dragon Pulse / Thunderbolt / Surf / Psychic
Jellicent / Water Absorb / Timid @ Water Gem
IVs: special flawless
EVs: 4 HP 252 SpA 252 Speed
- Water Spout / Shadow Ball / Ice Beam / Energy Ball
Heatran / Flash Fire / Timid @ Leftovers
IVs: something like... 27 / ? / 15 / 31 / 26 / 27 (not RNG'd)
EVs: 252 SpA plenty of speed the rest in HP
- Flamethrower / Earthpower / Toxic / Protect
- Basically Fake Out something and hit something hard on first turn to gain the upper hand
- I wanted to use Ambipom here instead of other fake out users, because Ambipom is the strongest fake out user that outspeeds Latios (Purugly and Persian are the other two), so even after a fake out, Ambipom can U-Turn for some damage on the same turn that Latios uses surf (and obviously Jellicent switches in for Ambipom if I'm using surf), so that is handy.
- Jellicent isn't that amazing, but it does have really good resistances for my team. Jellicent switches in on fighting (or STAB normal) moves on Ambipom plenty of times, or ice/bug moves for Latios, or water moves for Heatran.
- Heatran is another thing that has great resistance combo with Jellicent and Latios, resisting bug, ghost, ice, dark, grass, dragon (though dragons are just handled with Latios most of the time since Heatran lacks HP Ice or Dragon Pulse)
- Toxic on Heatran is mainly for Stallish pokemon, which I can generally ignore after getting a toxic in. It's especially important, because Ambipom, my only physical attacker, does not attack super hard and sometimes it does faint before the end of the battle.
How I lost:
At battle 101, hm... let's see how much I remember. I think it went something like this:
Leads were Electivire and Manectric. The other two were Durant and something else I think, but it basically came down to one misplay where Heatran should have switched out for Jellicent to take Electivire's Earthquake while Ambipom's Return KOs Electivire the turn after, but instead Heatran fainted and so Durant was able to KO Ambipom with Power Herb dig. Jellicent survived a Tpunch (with like 6HP left) and Shadow Balled Electivire to death as Durant used dig, so obviously Jellicent faints the turn after. Well, Dig could have missed from Hustle I guess, but it didn't happen. I know that my Heatran with Protect walls Durant (after the Power Herb was used up), so should have switched him out.
... I probably remembered some of that wrong, since it doesn't seem quite right (Durant could have targeted Ambipom with dig and I would still be left in a similar situation). Anyway I just remember it was something like that where if I switched to Jellicent I would have had a much higher chance of winning.
- Yeah definitely take LO off Dragonite. Having LO on Dragonite loses the whole point of using Multiscale.
- Outrage is a move that does not let you choose your target in Double, so it might not be such a good move to use since it only targets the right opponent half the time.
- Not sure if Dragonite will really have time to Dragon Dance. Even with Multiscale, if it's double targeted, it still might just faint (like a fast random attack breaking Multiscale followed by an ice attack). Not saying it never works, but you want to minimize your risk, so I'd advise not having DD. Not having DD and outrage and LO does reduce Dragonite's power by a lot though. Maybe you can consider mix nite with Draco Meteor...
- Last year I used this moveset at VGC to some success: Dnite @ LO - Superpower / Draco Meteor / Extremespeed / Protect. Obviously that was with inner focus since 5th gen wasn't even out yet (Superpower is 4th gen only move). DM hits things really hard, and even after SpA drops, there's still ES and Superpower to work with (or even after attack drop from superpower, DM's still just as powerful). I actually specifically wanted Inner Focus to prevent fake out flinch too. Heh, whatever works for you. Only Extremespeed is a must on any Double Battle Dragonite imo, anything else goes. If you do want to outspeed Weavile after one DD you need 236 Speed EVs.
- Well, here's a thought... if you think steel types are handled fine, then Dragonite can just have DD / DM / Dragon Claw / Extremespeed and keep Multiscale while holding draco plate or white herb.
- Gengar seems like an ok replacement, but just keep in mind that Gengar can only switch in on predicted EQs and Fighting moves aimed at Terrakion... which I didn't think you plan on switching out anyway. So maybe that'll be ok.
Anyway good luck.
