Unlike most, I chose to have my delibird have hustle because of his poor attack power...
Delibird @ choice band, choice scarf, or focus sash
Ability: Hustle; raises delibird's attack
EVs in speed and attack
Aerial Ace - STAB, makes up for Hustle's reduced accuracy
Ice Shard - STAB, Priority
Bestow - If you are using a choice band or scarf, bestow will give the item to your opponent, confining them to the use of only one move. Good against set up Pokemon.
Brick break/Ice Punch - Brick Break : coverage, Ice Punch: STAB, good against slow enemies that won't be defeated by Ice shard
