Deck Evolution: Reveal the top card of your deck. If that card is a creature, put this creature into the battle zone on top of the revealed creature. If the revealed card isn't a creature return this creature to your hand. When you put this creature into the battle zone, search your deck. You may take 1 card with "Sword Flash Dragon" in its name and put it into your hand. Then, shuffle your deck. All of your creatures with "Sword Flash Dragon" in their names gain "Speed Attacker".
