Shadow



Shadow is a static ability that means the the affected creature can only block, or be blocked by other creatures with shadow.

Example
Aaron is attacking with an Augur il-Vec and a Canyon Minotaur, and Natalie controls a Drifter il-Dal and a Grizzly Bears.

The only creature that can legally block Augur il-Vec is Drifter il-Dal, as they both have shadow. The Grizzly Bears does not have shadow so it cannot.

Similarly the only creature that can legally block the Canyon Minotaur is the Grizzly Bears, as the Drifter il-Dal has shadow.
