Banish all LIGHT Machine monsters from your GY and your face-up field; Special Summon 1 Level 6 or higher LIGHT Machine monster from your hand, ignoring its Summoning conditions, and if you do, its ATK/DEF become equal to the number of monsters banished to activate this card x 500, also it is unaffected by card effects, except its own and this card's. You cannot Special Summon other monsters the turn you activate this card.
