If a Synchro, an Xyz and a Fusion Summon are performed on the same turn (in this order), it is possible to Special Summon essentially any monster from the Deck.
This card can be combined with monsters that provide draw upon being Synchro Summoned, such as "Stardust Charge Warrior" or "Ravenous Crocodragon Archethys". If this card's effect is activated as Chain Link 2, it is possible to draw any Monster Card.
