Spell Wall

When activating "Magical Barrier", you choose which "●" effect to activate.

Regardless of which "●" effect you choose to activate, the effect "After this card's activation, any damage your opponent takes for the rest of this turn becomes 0" is applied.

The effect "● This turn, the Normal, Flip, or Special Summon of your Spellcaster monsters cannot be negated, also your opponent cannot activate cards or effects when your Spellcaster monster is Normal, Flip, or Special Summoned" does not target. (Your opponent cannot activate cards like "Torrential Tribute" when a Spellcaster monster is Normal, Flip, or Special Summoned, but they can activate Spell/Trap/Monster effects during other times, such as the Main Phase or Battle Phase.)

The effect "● Target 1 Spellcaster monster you control; if it attacks this turn, your opponent cannot activate cards or effects until the end of the Damage Step" targets 1 face-up Spellcaster monster in your Monster Zone. (If this effect is applied, your opponent cannot activate Spell/Trap/Monster effects from the time the targeted monster declares an attack until the end of the Damage Step.)
