When this creature attacks, reveal the top card of your deck. If that card is a Fire Bird, you may put it into the battle zone. If that card is a Dragon, destroy 1 of your opponent's creatures with 4000 power or less. If that card is "Überdragon Sunburst NEX" you may put it on top of this card. (If you don't put the revealed card into the battle zone, return it to top of your deck face down.)
