Card Rulings:Secret Sanctuary of the Spellcasters

OCG Rulings

• This effect can be activated during the Damage Step.

• During the turn in which the "That monster cannot attack or activate its effects this turn." effect is applied, Continous Effects and effects that don't start a Chain Link are still applied.

• If you control "Secret Sanctuary of the Spellcasters" and you perform a Synchro Summon of a Spellcaster-Type Synchro Monster sending all your face-up Spellcaster-Type monsters to the Graveyard, since there is a period in which you do not control a Spellcaster-Type monster when you perform the Synchro Summon, "Secret Sanctuary of the Spellcasters" is destroyed. Also, if you control "Secret Sanctuary of the Spellcasters" and you perform an Xyz Summon of a Spellcaster-Type Xyz Monster using all your face-up Spellcaster-Type Monsters as Xyz Materials, since there is a period in which you do not control a Spellcaster-Type monster when you perform the Xyz Summon, "Secret Sanctuary of the Spellcasters" is destroyed.

• If "Forbidden Lance" is activated in a Chain to the effect of "Secret Sanctuary of the Spellcasters", targeting the monster that was Normal or Special Summoned, that monster is not affected by the effect of "Secret Sanctuary of the Spellcasters". (It can attack or activate its effects.) Also, if "Forbidden Lance" is activated targeting a monster that is already affected by the "That monster cannot attack or activate its effects this turn." effect of "Secret Sanctuary of the Spellcasters", that monster still cannot attack or activate its effects.
