It also inspires the magic of the Orzhov, such as is visible on Gift of Orzhova.
But obviously stained glass has appeared in Magic cards for many years. Take for example the Portal Second Age card Temple Acolyte.
Perhaps the currently most famous piece of stained glass in Magic is the terrifying view on Endless Ranks of the Dead.
Or the more abstract Halcyon Glaze. Halcyon is a term that refers to a period in the past which was idyllic and happy. Not that that necessarily explains this beautiful art.
To the much more recent example Fires of Undeath, which features a more monochromatic stained glass example.
There are a number of other examples of cards featuring stained glass. Have a favorite I don't include here? Tweet me or send me a feedback email below!
