Lucky Board and Treasure of the Sage is my all time favorite event! However, it is also dependent on what you need. Whether you need power or ninja; sometimes saving your coupons for an event where you go, "I must have it", is better then using it on something you don't like. Yes Lucky Board and Treasure of the Sage is historically very good events, but it doesn't mean it is the best event for you. You will need to figure out what you need and what you want to aim for, then you can save up for that goal.
