Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Activate 1 of these effects. Your opponent takes no further damage this turn. ● During this turn, no Summon of a Spellcaster-Type monster can be negated, and when a Spellcaster-Type monster is Summoned, your opponent cannot activate cards or effects. ● Target 1 Spellcaster-Type monster you control; if it attacks this turn, your opponent cannot activate cards or effects until the end of the Damage Step.
