You can also Xyz Summon this card by using 1 face-up "Number 4: Tesseract Dragon" you control as the Xyz Material. (Xyz Materials attached to any of this card's Xyz Materials also become Xyz Materials on this card.) This card cannot be destroyed by Spell/Trap effects. You can detach 1 Xyz Material from this card; banish 1 card your opponent controls, 1 random card from their hand, and 1 card from their Graveyard, then if 1 card of each (Monster, Spell and Trap) was banished this way, double this card's ATK until the end of this turn. You must have 1000 or less LP to activate and resolve this effect.
