If a "Kshatri-La" Xyz Monster is on the field: Make both players banish monsters from their field face-down so they control only 1. If this card becomes banished: You can target 1 "Kshatri-La" Xyz Monster you control; add 1 "Kshatri-La" monster you own attached to it to your hand, then you can Special Summon it from your hand. You can only use each effect of "Kshatri-La Big Bang" once per turn.
