Clarifications on individual rules

• Historical card erratas are used.
• The Spell/Trap restrictions limit card activation attempts. If the activation or effect of your Spell/Trap Card is negated you can not attempt to activate another Spell/Trap Card for the rest of the turn.
  • After 2015 P1 this ruling is reversed: The amount of successful activations is limited and if the activation of a card is negated you can attempt to activate another one. This does not apply to effect negations; If the effect of your Spell/Trap is negated you can not activate another one.
• Tribute Summoning
• Treating Tribute Summons as a Normal Summon is not optional; You can not tribute monsters to Normal Summon a high-level monster unless its card text allows or requires that.
• Monster with an effect that triggers on their own Tribute Summon can not active this effect when they are Normal Summoned (Example: Monarchs).
• Monster with an effect that allows them to be Tribute Summoned with more Tributes than necessary can either be Normal Summoned without this effect or Tribute Summoned with this effect by tributing the specified amount of monsters (Example: Moisture Creature).
• Monster with restrictions on their Tribute Summon regarding amount and type of Tributes can only be Tribute Summoned by tributing the necessary Tributes (that means Normal Summoning without Tributes is not allowed.)
• For Field Spells the official TCG rulings at that time apply.
• Activating a Pendulum Scale does not use up your single Spell Activation; Your single Spell Activation can not be used to activate a second Pendulum Scale.
