Now I know that Dueling goes on.
DUNE-JP067 アクアの輪唱 Aqua no Rinshou (Aqua Round)
(1) Banish 1 card from your hand, and if you do, during your next Standby Phase, you can add up to 2 cards with the banished card’s name from your Deck to your hand. If this card is activated while your opponent controls no cards, you cannot activate cards, or the effects of cards, with the banished card’s original name for the rest of this turn.
Note: A Round is a song that is sung by groups of people with each subset of people starting at a different time. Considering the artwork, it’s also referring to the other meaning of 輪唱, “trolling”. The girls got issues with one another.
