Example Post (From one of mine in RU):

Typhlosion @ Choice Scarf
Trait: Blaze
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Eruption
- Fire Blast
- Focus Blast
- Hidden Power [Grass] / Hidden Power [Rock]
Why it's bad:
I notice a lot of people run a Choice Scarf on Typhlosion. Typhlosion's former poor reputation in RU comes from this set. One may think that Typhlosion's absurd power STAB and good Special Attack and Speed make it a good revenge killer, right? Well, it's not. Why? Well, firstly, it's weak to hazards of all kinds, and it will usually get worn down really quickly by them. Typhlosion is also somewhat lacking in power, so resists such as Druddigon and Slowking can come in and not mind it. Priority exists, particularly from Absol and Entei, and Typhlosion is useless after it can't spam Scarf Eruption anymore, which is a large portion of the time. Typhlosion also can't do much to a lot of defensive teams, which is kinda bad. There's Choice Specs Typhlosion, which is another story.

Typhlosion @ Choice Specs
Trait: Blaze
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Eruption
- Fire Blast
- Focus Blast
- Hidden Power [Grass] / Hidden Power [Rock]
Why it's better
It's the same set, so what? Take out a Scarf and replace it with Specs, and Typhlosion's a whole different story now. Typhlosion makes a great wallbreaker, abusing his great Special Attack and absurd power Eruption to put massive dents in opposing teams. For the record, he 2HKO's Entei and Lanturn after SR! He has great power, and his Speed tier is already good enough to suffice, and it doesn't matter if you can't revenge kill Scolipede and Sceptile. He has a Blaze boosted Fire Blast to hit hard with if he gets worn down, with patches up the Eruption mechanics. With the power, you can see why Specs Typh is so much better than Scarf.
This is just an example, and your post doesn't have to be like this, but please try to explain your thoughts on why something is bad.
Some things I'd like discussed to begin:
- Ambipom
- Claydol
- Choice Scarf Flygon
