Gwent : The Witcher Card Game 

https://www.playgwent.com/ko

*Battlefield: Rows where you can place cards. It consists of a total of 4 rows, including allies and enemies, with 1 melee row + 1 ranged row for each ally and enemy. Even the same card has different abilities depending on which row it is placed in, depending on melee / ranged.
*Graveyard: Cards that are stacked face down on the left side of the hand. When a round ends, all cards collected from the battlefield are stacked in the graveyard. However, if the status is extinguished or exiled, it will not be stacked in the graveyard.
*Hand: Cards that are given at the beginning of each round and can be played on the battlefield, but are still in your hand and have not yet been played. Only you can see your cards, and you cannot see the enemy's cards. There is no separate sorting function.
*Deck: Cards stacked face down on the right side of the hand. Cards that are likely to come up in your hand in the next round.
*Turn: When it's your turn to play a card. The principle is that you can play 1 card from your hand on your turn, but it's possible to have special cards that create other cards, etc.
*Round: Gwent decides the winner through a total of 3 rounds. Each round is a separate battle, but it's not completely irrelevant because special cards can persist or be used in battle through the graveyard/deck.
 
[Card types]
*Unit card: Refers to one card placed on the battlefield, regardless of whether it is an ally or an enemy. The original power is displayed in the upper left corner. It can be amplified or reduced by bleeding.
