Dead Man's Chest

As long as Dead Man's Chest is an Aura, it has "Enchanted creature has indestructible and 'this creature can't be sacrificed.' When Dead Man's
Chest becomes unattached from enchanted
creature, sacrifice that creature."
{2}{g}, {t}: Dead Man's Chest becomes an Aura attached to target creature you control for as long
as you control that creature.
