Forum:Cold wave Q

ok i have read through most of the forum posts and this is still not clear to me if my opponent plays cold wave, can i activate anything later on in the turn? i have friends who said that you can, since the card says neither player can  play  any card but activating pre-set cards are different from playing, which according to them is a term refering to playing spell cards from the hand can anyone clarify it for me?24.205.27.112 07:58, April 8, 2010 (UTC)
