Card-specific notes from database

• The battle destruction protection from the first effect applies even if adding the Spell/Trap to the hand is unsuccessful (Konami neuron).
• The battle destruction protection also applies to Power Patron Link Monsters that become face-up in your Monster Zone after the effect resolves, until the end of the next turn (Konami neuron).
• If this card is banished as cost for its first effect as Chain Link 1, and an Xyz or Link Monster is Special Summoned at Chain Link 2 or higher, its second effect can be activated in a new Chain because it was already banished when the Special Summon occurred (Konami neuron).
