Curse of Sand was the third set in the Naruto CCG and like the previous set before it Coils of the Snake it brought another new mechanic into the game. "Growth" allowed your ninjas to "Grow" by sending a copy of the ninja on the field to the chakra area to play a ninja with a same name who had the "Growth" characteristic and that ninja would gain a "Growth Coin" which gave the ninja +1 attack and +1 support.
