Forum:Phantom of chaos

i beleive i know the answer to this but some people are questioning me. does phantom of chaos have to pay costs to activate the effect of a monster it has copied, lets say i summon phantom and remove dark armed dragon do i have to remove cards to activate the effect of d.a.d.? or can i just say activate, activate, activate and blow up every card on my opponents field?
