Netrep Q&As
Q: “Cold Wave” negates continuous spell and or trap cards, this includes equipments too, right? A: “Cold Wave” makes it so you can't "play" (activate) or "Set" Spell or Trap Cards, and extends to "activating" effects of Spell/Trap Cards already on the field. But “Cold Wave” will not negate continuous effects of cards like “United We Stand” that were in play BEFORE “Cold Wave” was activated. bishop, 12/08/2003
