OCG Rulings

  • The ATK and DEF which are replaced by the effect of "Inverse Universe" remain as long as the monster remains face-up on the field. If the monster is flipped face-down or is removed from the field, then its ATK and DEF return to their original amounts.[7]
  • If a monster has its ATK and DEF switched by "Ojama Country" and is then affected by "Inverse Universe", then its ATK and DEF are switched again. Afterwards, if "Ojama Country" is removed from the field or if there are no longer any face-up "Ojama" monsters on the field, then the ATK and DEF switched by "Inverse Universe" do not change.[8]
