When this unit is placed on (VC), you may pay the cost. If you do, your opponent puts all of his or her rear-guards on the bottom of his or her deck in any order. Then, if you have a face up card named "Interdimensional Dragon, Chronoscommand Dragon" in your G zone, you choose up to two of your rear-guards, and put all of your rear-guards other than those units on the bottom of your deck in any order, and if you do not, you put all of your rear-guards on the bottom of your deck in any order.
