【Regarding "Must be Fusion Summoned (from your Extra Deck)":】
This is not treated as an effect.
The only way to Special Summon this card from the Extra Deck is by Fusion Summon.
If this card was Special Summoned by its proper method and then sent to the Graveyard or banished face-up, you can Special Summon this card with the effect of another card.
【Regarding the ① effect】
This is a Quick Effect that can be activated in the Monster Zone.
It can be activated while you have at least one "Shaddoll" card in your hand.
It can be activated against a Special Summon that does not create a Chain Link, excluding Special Summons performed by resolving an effect.
When resolving the effect, perform the action "negate the Special Summon, and if you do, destroy that monster," and if the destruction is successful, then perform the action "send 1 'Shaddoll' card from your hand to the GY." (These actions do not occur simultaneously.)
Even if you have no "Shaddoll" cards in your hand at the time of resolution, the action "negate the Special Summon, and if you do, destroy that monster" is still performed.
It can also be activated when two or more monsters are Pendulum Summoned. In that case, all monsters whose Pendulum Summon was negated are destroyed.
【Regarding the ② effect】
This is a Trigger Effect that can be activated in the Graveyard.
It can be activated even if the condition is met during the Damage Step.
