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.
The monster effect "①: You can banish 2 'Noble Knight' monsters from your GY; Special Summon this card from your hand or GY" is an Ignition Effect that activates in the hand or GY. (This effect does not target. Also, when activating this effect, you banish 2 "Noble Knight" monsters from your GY as the cost. You cannot banish the "Noble Knight Eachtar" that activated this effect itself.)
The monster effect "②: The Synchro or Xyz Summon of a 'Noble Knight' monster that used this card as material cannot be negated, and your opponent cannot activate cards or effects when that monster is successfully Special Summoned" is an effect that is not classified as an Ignition Effect, Trigger Effect, Quick Effect, or Continuous Effect.
Neither you nor your opponent can negate a Synchro or Xyz Summon that used "Noble Knight Eachtar" as material by activating "Solemn Judgment" or similar cards.
If a "Noble Knight" monster that was Synchro or Xyz Summoned using "Noble Knight Eachtar" as material has an effect that activates when it is successfully Special Summoned, that effect can be activated as normal.
