[]:When you play a "Zoltraak", [], this unit, it attacks your opponent's vanguard, and this unit's drive becomes 0 until end of that battle. At the end of that battle, this unit. If your opponent's vanguard is grade 3 or greater, its drive becomes 1 instead of 0. (This attack cannot be boosted) []:[Discard a card from hand], look at the top seven cards of your deck, choose up to one grade 2 or less card with "Frieren", "Stark", "Sein", "Übel", "Land" or "Heiter" in its card name from among them, reveal it and put it into hand, and shuffle the deck.
