The hand is where each player keeps the cards currently available to them. The player can see their hand face-up at the bottom of the screen, while the opponent's hand is shown face-down at the top of the screen.
- To see the number of cards currently held in your hand, hover your cursor over your deck.
- To see the number of cards in the opponent's hand, hover your cursor over the opponent's deck.
The player can only play cards that are currently in their hand. Players place cards into their hand through drawing cards from their deck. A few other methods such as return effects and generate effects can also add cards to the player's hand.
Players can have a maximum of 10 cards in their hand at any time, unless was played. Attempting to add a card to the hand when it is already full will cause that card to be destroyed, sometimes referred to as overdraw. Cards destroyed in this way are revealed to both players.
Playing a card removes it from the player's hand, and puts it into play. This is the main way for players to empty their hand. The only other way is through discard effects, which force the player to discard cards from their hand without playing them. Like overdraw, discard effects reveal the discarded cards to both players.
Hand tracking is a strategy used to track and predict what cards are in the opponent's hand. This can also be done during the mulligan phase to see how many cards the opponent kept in their opening hand.
