• Tap each permanent target player controls with exactly one word in its name.
• Discard all the cards in your hand, then draw that many cards.
• Return target instant or sorcery card from your graveyard to your hand.

Boing!

Return target creature to its owner's hand, then roll a six-sided die. If the result is 3 or less, scry a number of cards equal to the result.

Denied!

Choose a card name, then target spell's controller reveals their hand. If a card with the chosen name is revealed this way, counter that spell.
