Angel art is tall.
Of course, the color white is the champion of all that is just and righteous, and so the natural mode of illustrating an angelic white paragon of these virtues is with a lot of verticality. Unfortunately, while the art box of Magic cards has grown in size with the recent change in card face, it's still a mostly horizontal rectangle. What's an art director to do?
Not much to do but crop, and frown.
But lucky you: you clicked on Magic Arcana today, so you get to see a few of these screen-dominating Angels in all their glory.
Prepare to scroll, folks.
