Card-specific notes from database

• (YGOResources) You cannot Fusion Summon a "Mirrorjade the Iceblade Dragon" using a face-up "Mirrorjade the Iceblade Dragon" on your field as material.
• (YGOResources) If you take control of an opponent's "Mirrorjade the Iceblade Dragon" while you already control one, the one you gained control of is immediately destroyed (not by a card effect), and its Trigger Effect cannot be activated.
• (Konami neuron) If the activation or effect of the Quick Effect is not negated, the "cannot use this effect next turn" restriction applies even if no card is successfully banished. If the activation or effect is negated, the restriction does not apply and it can be activated again next turn.
• (YGOResources) The Quick Effect cannot be activated while an effect like "Macro Cosmos" is applying, as the cost to send a card to the GY cannot be paid.
• (Konami neuron) The Trigger Effect can be activated if this Fusion Summoned card is sent to the GY or banished face-up by an opponent's card while in its owner's Monster Zone. It cannot be activated if returned to the Extra Deck, banished face-down, or if it leaves the field while controlled by the opponent.
• (Konami neuron) The Trigger Effect can be activated if the opponent Tributes this card to Special Summon a "Kaiju" monster or uses it as Link Material for "Underworld Goddess of the Closed World".
• (Konami neuron) The Trigger Effect can be activated if this card's Flip Summon is negated and destroyed by a card like "Solemn Judgment".
• (Konami neuron) The End Phase destruction will destroy monsters that are "unaffected by activated effects", because the destruction is not applied during the resolution of the Chain Link.
• (Konami neuron) Effects like "Stardust Dragon" or "My Body as a Shield" cannot be chained to the activation of the Trigger Effect, because it does not destroy cards at resolution.
• (YGOResources) The Trigger Effect can be activated even if this card was flipped face-down, or temporarily banished and returned to the field, before leaving the field.
• (YGOResources) This card does not need to remain in the location where its Trigger Effect was activated for the End Phase destruction to apply.
