Does Nitro Warrior's first effect can only be used by the first attack or is applied to the second attack too? i mean...if i change a monster to attack position, nitro warrior will still attack it with the 1000 atk bonus? and which of the 2 effect cant be negated by Star Dust Dragon? or both can be negated?
