I am confused about how this card works. If a monster is special summoned that turn then am I free to use it on any monster that activates an effect? Can this card negate Stardust Dragons effect of special summoning at the end phase? Would this work on a Gorz or Blackrose? 24.129.32.33 (talk) 07:07, July 2, 2011 (UTC)
