Vision Charm

Instant, U (1)
Choose one - Target player puts the top four cards of his or her library into his or her graveyard; or choose a land type and a basic land type, and each land of the first chosen type becomes the second chosen type until end of turn; or target artifact phases out. (While it's phased out, it's treated as though it doesn't exist. It phases in before its controller untaps during his or her next untap step. )¹
