Tier 0 (CS Users, and >130 base speed)
+nature/252: A pokemon with a beneficial speed nature, and 252 EVs in Speed.
252: A pokemon with a neutral speed nature, and 252 EVs in Speed.
CS: A pokemon holding a Choice Scarf.
One DD: A pokemon before or after one speed boost.
Two DDs: A pokemon before or after two speed boosts. Remember two speed boosts is equal to one use of Rock Polish/Agility.
(130): A pokemon with 130 base speed.
no-speed: The pokemon does not have a beneficial speed nature, or any speed EVs.
-nature/31IV: The pokemon has a nature that reduces its speed, but has 31 IVs in speed.
-nature/0IV: The pokemon has a nature that reduces its speed, and also has 0 IVs in speed.
How to use this list: Find the poke you’re building, and see how high on the list it can hit (searching on the page helps). Then, see how far you can go down the list without losing to someone you want to outspeed.
For example: Jolly (+Speed, -Sp.Atk) Garchomp with 252 EVs can hit 333 speed. But the next highest group is at 329 speed (neutral-nature Azelf/Starmie). So Jolly Garchomp can safely run 330 speed (240 EVs) and never lose any extra matchups.
Serebii’s D/P Stat Calculator lets you figure out how many EVs you’ll need to hit a certain speed. It’s also useful if you have a pokemon with a less than 31 IV in speed, or if your specific pokemon isn’t listed. However, keep in mind: if your pokemon has less than a 31 IV in speed, you will never be able to hit a +nature/252 speed listed for your poke!
Dragon Dance: you can find a target speed you’d like to hit after one Dragon Dance, and then multiply that target speed by 2/3. Rounding up the result will give your desired starting speed.
So if you wanted to hit 404 speed after one Dragon Dance (outspeed CS 252 Heracross), type this into your calculator:
404 * 2 / 3
to get 269.33 -> which is 270 speed.
Rock Polish/Agility/Swift Swim: you can choose a target speed after one use (or in the rain), and then divide in half. Rounding up the result will give your desired starting speed.
So if you wanted to hit 419 speed after one use (outspeed CS 252 Moltres, Lucario, PorygonZ), half of that is 209.5 -> so you’d want 210 speed.
