Choice Band:The Pokemon's Attack is 1.5x, but it can only use the first move it selects.
Choice Scarf: The Pokemon's Speed is 1.5x, but it can only use the first move it selects.
Choice Band raises your attack for physical attacker and Choice Scarf raises speed. There is also Choice Specs which raises special attack by 1.5x.
Choice Scarf is if you want to be really fast and then outspeed the opponent and KO them. Choice Band is if you are a physical attacker and then your attacks will do way more damage. I like Choice Scarf better because it raises speed and let's me outspeed, and if my Pokemon has good attack or Sp.attack I can usually get the KO.Also if you use the items you can only use the move you select, but this can be reset by switching out. If you
use Fire Blast on Charizard with Choice Scarf, it can only use Fire Blast until you switch out.
Here is an example.
Metagross @ Choice Band
Ability: Clear Body
EVs: 252 HP / 252 Atk / 4 SDef
Adamant Nature
- Bullet Punch
- Earthquake
- Ice Punch
- Trick
He has physical attacks so Choice Band is useful and can make his attacks hurt.
Metagross @ Choice Scarf
Ability: Clear Body
EVs: 252 Spd / 252 Atk / 4 HP
Jolly Nature
- Earthquake
- Iron Head
- Trick
- Ice Punch
This guy is the same, but his Evs are different so he can outspeed the opponent and KO them, but they will not do as much damage. Metagross is slow but it is good with Scarf. Also I dont have bullet punch as it does more damage with Band and Iron Head's flinch chance has a greater chance of happening if I put a scarf and manage to outspeed.
Hope I helped!
