Through the Mind's Rift

Reveal a creature card from your hand or from
outside of the game and put it to the battlefield
face down attached to target creature as an Aura
enchantment with enchant creature. It has
"When enchanted creature dies, return this card
to the battlefield face up" and "Enchanted
creature can't be sacrificed."
Millions of revelations can speak to you through the
mind's rift, dancing across your soul like the feet of a
thousand rails.
