Rankle, Master of Pranks

As the first mode is performed, first the player whose turn it is chooses a card in hand without revealing it, then each other player in turn order does the same. Then all the chosen cards are discarded at the same time.

You can choose a mode even if some or all players will be unaffected.

If you really want, you can choose zero modes for Rankle's triggered ability, but carefully consider the hidden costs in not entertaining someone titled Master of Pranks.
