Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can banish 2 "Noble Knight" monsters from your GY; Special Summon this card from your hand or GY. You can only use this effect of "Noble Knight Eachtar" once per turn. A Synchro or Xyz Summon of a "Noble Knight" monster using this card as material cannot be negated, also your opponent cannot activate cards or effects when that monster is Special Summoned.
