(VC/RC):When placed, if you have a vanguard with "Star-vader" in its card name, COST , your opponent looks at the top card of his or her deck, and puts it on an open as a locked card. If that locked card was placed in the back row, you draw a card, and this unit gets +10000 until end of turn.
:If your opponent's vanguard is grade 3 or greater, and he or she has a locked card, all of your vanguards' original [Critical] become two.
