Rules Text: Cast Camouflage only during the declare attackers step.
This turn, instead of declaring blockers, the defending player chooses any number of creatures he or she controls and divides them into a number of piles equal to the number of attacking creatures. Assign each pile to a different attacking creature at random, and any creatures in that pile that can block the creature do so. (Piles can be empty.)
