If a monster is Special Summoned in the Battle Step before the Damage Step, can it declare an attack that turn?!
Stardust Dragon is attacked, then Assault Mode Activate Special Summons Stardust Dragon/Assault Mode before the Damage Step.
Yes. The original attack stops and you return to the Battle Step, so the newly Summoned monster can declare an attack.
