Cosmic Rift-Shaper

Protection from colored spells and abilities
When you cast an instant or sorcery spell, copy
that spell and you may assign new targets for
that spell. If it is colored, it becomes an
enchantment that can't be destroyed until the beginning of your next end step.
Sacrifice an enchantment: Search your library for
a colorless spell with converted mana cost 4 or less
and place it in your hand.
