Endless Shadows

Flying
At the beginning of each end step, if a creature
died this turn, you may create a token that is a
copy of Endless Shadows.
On the wings of despair does soar the veil of
darkness. And from its slumber, shall emerge a triumvirate shadow. Echoed in the harsh majesty of
their screams, an army shall form and capture the
skies, blanketed in death.
- Excerpt from "Blackened Tide"
