Drifblim Set for OU
With so much weather around, im truely surprised i haven't seen more of this kind of drifblim. He's great in the weather (or at least he's pretty awesome). Why does no one use this (though i admit its hard to get him to work properly).
Ability: FLARE BOOST
item: Flame Orb
nature: Modest (+SpA, -Att)
ev spread: 4 HP/252 SpA/252 Spe
I know there's a lot of moveslots, so bare with me...
The idea here is that Drifblim with Flare Boost and a modest nature is actually quite powerful, almost as strong as Kyogre. It also has a decent amount of HP, making it somewhat bulky (but alas, its still quite fragile). also, this moveset abuses the fact that it has weather ball, which is the only good pokemon that can actually use that move and do some damage.
Trick is obvious...in a last ditch effort to burn an opposing pokemon, you trick your flame orb onto another pokemon. It's tough to pull off, but with the right kind of support (cough cough Tailwind) you can do it. Its also ok because you might just be able to burn something slower than Drifblim as well.
Hex is a special Ghost type move that does 50 base damage, but its useful because it doubles its power when the opponent has a status condition. So...Toxic Spikes support is needed for this move, but you have to take out the opponents rapid spinner first.
Likewise, Drifblim can create/stop opposing weather pokemon, depending on what your weather is. Drifblim can learn both Rain Dance and Sunny Day, so either one of those will work.
Like I mentioned before, Drifblim can also learn Tailwind, though its not the best user by any stretch of the imagination. It has to be faster than its opponent in order for this to work, so you would have to set up on something like a Ferrothorn.
Shadow Ball is obvious. Consistent STAB damage that should hit hard anything that doesnt resist it. point made.
Thunderbolt/Thunder will depend on the weather you are using. Thunder for rain, Thunderbolt for everything else. Thunder hits harder and gets the 100% accuracy in the rain (plus rain is more common). likewise, you can use Thunder as an anti-rain pokemon if you are using something other than rain, though you loose accuracy if you win the weather war. It hits hard as well.
The last move, the holy grail of this set...weather ball. This is such a great move that Castform thought it had ALL to itself. but not the case. the great thing about weather ball is that it does 100 Base damage in weather. No matter what the weather is. It then becomes the appropriate type that the weather is, aka Water for rain, Fire for sun, Ice for Hail, and Rock for sandstorm. (dont quote me on this) In everything except sandstorm, because its the same type as the weather, it gets its power doubled. So its pretty much, a 200 base power move at its disposal. And you get to chose the type of move.
This set NEEDS support for it to work, and the entire team needs to be built around it. Tailwind support is HUGE, Dual-screens is also huge (espy is drifblims best friend), and toxic spikes/rapid spinner is also a huge benefit.
I wish i could see more of you drifblim...you are my favorite anti-metagame pokemon.
