Visions is quite possibly the best Magic expansion to date. It continues on the popular themes and mechanics of Mirage, such as Flanking, Phasing, the Charms, and it even adds another "instantment" (enchantment that can be played as an instant). It also introduces a set of creatures that have a helpful effect when they come into play.

Notable Cards:
City of Solitude Buy, Sands of Time Buy, and Eye of Singularity Buy have all proven to be powerful Visions cards. They each have the ability to stop many of the popular combo-decks in their tracks.
