Ok, first, I'd like to thank those who enjoyed the article and the effort I put into it, even those who disagree with the occasional matchup analysis.
SF Gengar isn't really that relevent vs Jumpluff. If the Jumpluff player is sloppy and doesn't adjust their own game plan to how you approach the matchup, then sure, it can give you an edge. Even with that "edge" over the standard approach, it isn't enough to let you win even close to 50% of the games. Let me point out a few problems.
First, at best, you get one turn of the "huge poltergeist". Now, thats even assuming you get a "huge poltergeist" at all. I run a 3-3 Claydol line, which helps to manage the # of trainers in my hand. I can also use my Supporters unhindered. Toss in the fact I can use Chatot to "set up" past the trainer lock to manually get my evolutions. Regice also serves as a potential "trainer dump". If you think I can't keep my hand down to less than 3 trainers, and keep a Crobat G active to take the hit, your dead wrong.
The next question is, you kill my guy first, and then I just go off normally. Now what? You can't even re-lock my trainers, and my gameplan is unhindered. Being up a prize isn't going to magically make you a favorite vs Jumpluff when your not able to score one hit KOs during the game. If you want to sit there and 2 hit benched Pokemon while I take a prize each turn I'm more then ok with that. I won't even need to take Fainting Spell flips either due to fancy crobat work. I guarantee you that regardless of "approach" that Gengar is this deck's easiest matchup. I've had bad starts, gotten trainer locked, and fallen behind 2 prizes vs a deck running Dusknoir and 2 Mr Mime and still beaten it comfortably. There is no possible way that Gengar, outside of a huge effort JUST to tech vs Jumpluff and ruining most if not all of it's other matchups, beats Jumpluff.
Gyarados: Baby Mario: I know that in the UK Gyarados builds are actually better. I know Tom Hall and Sami Sekkoum both have very good Gyarados lists, running the Luxray, and a bunch of Warp Energy. Some of the top players have done the same, but they also don't usually choose to run Gyarados, A vast majority of the ones I'd seen from States, and those my friends have played vs around the country, do not yet run these gusting effects. Luxray is a fantastic addition to Gyarados. Reversal is simply worse than Luxray.
In the instance where the player ( I'm sorry I forget the user name, but I can't scroll back a page to check ) killed 3 support Pokemon before getting blown out by the near solo- Gyarados problem. That can be avoided by not killing all of the support Pokemon so aggressively too. You can really adjust your approach in the matchup here. You could start using Leaf Guard to "not kill" Pokemon which can later be stolen as Crobat kills. ( leaving you at risk to SSU to a degree, but thats one less SSU on their Gyarados once it gets down to just Gyarados. ) If you use the Leaf Guard tactic, don't just start off with it. Take at least a prize first, so your ahead in prizes, and force them to over extend into getting a Jumpluff kill. During this attempt to bide your time, start to power up a Luxray GL. This will let you threaten a Gyarados for a OHKO. Well, once you use Crobats and Belt.
By taking early prizes, it allows you to try the "two hit/force SSU" approach. By hitting them once, it forces them to play a bench, and then hit a SSU, which leaves a Pokemon stranded on the bench. Thus, every time they "reload" a Gyarados with SSU, it gives you another kill target. ( Possible complication is if they use an SP Pokemon + PokeTurn, but thats a good reason to use an occasional Leaf Guard to force Crobat/Turn usage, or Lux/Turn usage )
As for the 2 Gyarados approach: I don't actually like that tactic very much. First, limiting it to 60 damage does a couple of bad things. First, it makes it so Luxray GL Lvl X is NOT getting KO'd by Gyarados one hit. ( I mean theoretically yes, but definitely not a worrying % of the time ). It also means to really be killing Jumpluff, your forced to use an Expert Belt, and a Crobat. Now, by using this approach you are clogging your bench. This makes it so Jumpluff can KO Gyarados easier. Its also forcing down Expert Belt, so it forces Gyarados to expose itself to the two prize deficit.
If you really want to secure your Gyarados matchup, with a Lucario GL to give Luxray double weakness, or a Giratina ( Let Loose ) help dramatically. Hitting Giratina after they limit their bench cripples their ability to play benchless as their SSUs and PokeTurns all get shuffled back in. It also " buys a turn" after they Sableye early.
If Jumpluff really wants to beat any of the non awful matchups ( Kingdra, Charizard, etc ) it can definitely mildly adjust the list to do so.
