Normally, you can ask to be loaned a fund for the ball. Please note that a creature registered at the ball cannot be modified. So once the ball is over you remove the loan background, put it on one of your rank 1 duplicates and send it back to the person who lent it to you.
But there were a few misses and the loan funds were never returned. So now the majority of people prefer to exchange the background for an equivalent rank 4 creature, another background or decoration of the same value.
