Whenever you attack you may create a clue
token and choose a card in your hand. Target
opponent guesses whether or not that cards
mana value is less than or equal to the number
of artifacts you control, then reveal that card.
If they guess incorrectly you may play that
card without paying its mana cost. If they
guess correctly distributed X crack counters
amount permanents you control where X is
that cards mana value.
