Rulings
- While Non-Spellcasting Area is active, you cannot use face-up monsters on the field, except Effect Monsters, for Polymerization or Ritual Spell Cards.
- While Non-Spellcasting Area is active, no Spell Card, including Raigeki or Equip Spell Cards, can affect a monster, unless it is an Effect Monster.
- While Non-Spellcasting Area is active, and only one player has Effect Monsters on the field, you can activate "Creature Swap" but its effect will be negated because none of the non-Effect Monsters can switch control due to a Spell Card’s effect.
- The effect of "Non-Spellcasting Area" includes Ritual Monsters and Fusion Monsters that do not have effects, as well as Monster Tokens.
