I'm gonna give ChestoRest Drifblim a try. Sounds good. Someone posted it, but I had it in mind since I saw here there's a chance Drifblim will drop.
				
			Multi-Fire often doesn't have a way to deal with Rain Dance. They're less likely to carry bulky Water resists and more likely to have something like Quagsire, easily dispatched by HP Grass. Fast Swift Swimmers like Floatzel will 6-0 Leman's team, for example.
Ice-eyes said:There are a few interesting things to note.
Firstly, balance seems pretty dead. Miltank can be easily replaced with things like Gligar, but there's no like-for-like replacement of Slowking. Nothing can match its bulk on both sides of the spectrum, perfect resistances for NU and respectable attacking power. It's clear that the old Medicham/Primeape/Miltank/Slowking/Skuntank/Espeon teams aren't going to work any more - they simply can't sustain a strong enough defensive core to make use of the team type worthwhile.
Secondly, Spike-Stacking is now viable. Its previous problems basically stemmed from the lack of good Spikers and Spinblockers in NU. There weren't good enough pokes to set Spikes up, and there wasn't a bulky but offensive Ghost that could help keep them up either. Dusclops had lackluster attacking power, killing momentum, while Haunter was incredibly frail and Pursuit-weak. Now, Qwilfish is again an excellent Spikes lead and Drifblim returns to fulfil the role of a threatening but durable spinblocker.
Magmortar is now incredibly strong - Thunder Wave Slowking was the best and most splashable way to keep it in check and now that Slowie's gone it's almost impossible to switch into. Whereas Slowking could threaten with Thunder Wave, there's nothing to stop Magmortar just switching out of Grumpig or Flareon. The latter is also extremely susceptible to being 2HKOd following Spikes/SR damage if it comes in on the wrong attack. Without Slowking, fire-types in general are much harder to check, though things like Mantine can take on Zard and Typhlosion - expect to see many teams like Leman's no. 1 triple-Fire.
Ninetales benefited hugely from the changes. Its big counter, Slowking, is gone and it's going to benefit from the fact that it's a good switch-in to Magmortar. In fact, there isn't anything comparable that can switch in without too much worry but still fit into an offensive team and pose a strong attacking presence. With its excellent Special Defense it can even take Thunderbolts and Focus Blasts, setting up Nasty Plot and threatening the opponent's team. Its general lack of power is also compensated for by Spikes. Magmortar is also an excellent teammate, able to break down special walls and lure in faster revenge-killers which the opponent can hopefully then be persuaded to sacrifice.
Sub + 3 Attacks Espeon is a lot stronger now. Last metagame, I thought it was almost the ideal set, with one problem - it had serious trouble with special walls, especially Slowking, because even with LO they weren't 2HKOd. Now, with Slowking gone and Spikes support available, Espy is incredibly good. It can be especially effective in combination with Drifblim - I've used something similar with Latias and Gengar in OU. If Espeon can Sub on their switch and kill Skuntank, Drifblim has a much easier time. Similarly, if Driffy can start setting up and kill ScarfApe or the Skunk when they inevitably come out, Espeon can destroy the opponent.
There are a host of other shifts in the metagame. Things that relied on setting up on Miltank or coming in on Slowking are less viable, Electric is not quite as good a STAB as it was and many physical attackers can bulldoze through the likes of Gligar when they couldn't 2HKO Miltank.
I have no idea why people don't use it outside of hail.
As I said, it's all about what part of the team it is, if you want a set-up sweeper, Kingler, Crawdaunt, and Whiscash could all go in that spot. If you want a good all out attacker Sharpedophile is the proper choice.You need to optimise EVs. You only need enough to beat Scarfed base 105s (Manetric), or 110s if you're really paranoid.
Sharpedo's immediate speed and power are what makes it so good.
I'm building a team around slaking, and am going with a moveset of return, night slash, and superpower. Since fire punch is totally unneded in nu, would rest be a viable option in the last slot? I'm packing a cleric, probably meganium, but it pretty much sucks, so if you can suggest a better one i'm all ears. Since slaking has massive bulk and is always switching, rest could be used when i switch in on something he forces out, right?
Wish Kanga/Lily don't have the same walling ability though, nor do they have Thick Fat.
I even saw a dragon dance latias once.
The problem is that the best way to counter rain is to carry a very lopsided team with 3 specific, stally pokemon to stall out the rain, and 3 sweepers to take out the team once rain goes down - which is not only diffucult to find dedicated walls, but thats the type of team totally countered by a 4 fires team. NU could become a rock/paper/scizzors metagame
Shedinja counters Rain Dance.
Fire counters Shedinja.
Rain Dance counters Fire.
We need some lizards and Spocks, or else this could get kind of dull.
