Liar's Pendulum

First you name a card. Then the targeted opponent guesses whether the card is in your hand.

After the opponent has guessed, you may reveal your hand. If your opponent was wrong, you draw a card. If your opponent was right, you don’t draw a card.

You reveal your hand only if you choose to, regardless of whether your opponent guessed right or wrong.

You can’t draw a card if you don’t reveal your hand.
