Forum:When can I activate Assault Mode Activate

Is there anyway that i would be able to activate assault mode activate trap card at the beginning of my opponents turn like on their draw phase or standby phase or at the beginning of their main phase 1...the reason i ask is because i run into the problem that i have a stardust out but then i get my assault mode too late when on the next turn my opponent can use a monters effect to destroy me before i can get assault mode out to negate their monster but the issue is not them destroying my stardust its destroying other monsters i may have on the field.
