{1}: Starting with you, each player may exile
a nonland card from their hand face down. Reveal the exiled cards. The owner(s) of the
card(s) with the lowest converted mana cost
casts it without playing its mana cost if able.
Put the rest of the cards revealed this way
into their owners' graveyards.
"Let us talk of humility."
